SSC CHSL Tier 1 2024 General Intelligence & Reasoning Questions with Solutions

Explanation

The series is formed by subtracting consecutive even numbers in descending order, starting from 12.

The pattern of differences between consecutive terms is as follows:

40 - 12 = 28 28 - 10 = 18 18 - 8 = 10 10 - 6 = 4 4 - 4 = 0

The differences decrease by 2 at each step: 12, 10, 8, 6, and 4. Applying this pattern, the missing number that correctly fits between 40 and 18 is 28.

Explanation

In the given pairs, the first and last letters are shifted by +7 in the English alphabetical order (L + 7 = S, F + 7 = M; T + 7 = A, Y + 7 = F). Applying the same logic to ZDMK, the first letter Z + 7 gives G, and the last letter K + 7 gives R, which uniquely identifies GNER as the correct option.

Explanation

The statement that some keys are chains means there is an intersection between the set of keys and the set of chains. Since all chains are locks, this entire intersection between keys and chains is also contained within the set of locks. This guarantees that some keys are locks, which means conclusion II logically follows. The statement that no lock is a rock only prevents the locks from being rocks, but it does not prevent the portion of keys that are not locks from being rocks. Therefore, we cannot conclusively state that no rock is a key, so conclusion I does not logically follow.

Explanation

The series decreases by consecutive perfect squares. The pattern of differences between consecutive terms is as follows:

129 - 1 = 128 (where 1 = 1²) 128 - 4 = 124 (where 4 = 2²) 124 - 9 = 115 (where 9 = 3²) 115 - 16 = 99 (where 16 = 4²)

Following this pattern, the next square to subtract is 5²:

99 - 25 = 74 (where 25 = 5²)

Explanation

The letter clusters in this group follow a pattern based on the alphabetical positions of their letters. The second letter is obtained by shifting the first letter forward by 9 positions, and the third letter is obtained by shifting the second letter forward by 7 positions.

For OXC, the alphabetical positions of the letters are O = 15, X = 24, and C = 3. Shifting O forward by 9 positions gives X (15 + 9 = 24). However, shifting X forward by 7 positions would yield E (24 + 7 = 31, which corresponds to position 5 after cycling through 26 letters). Instead, X is shifted forward by only 5 positions to get C (24 + 5 = 29, which corresponds to position 3). Therefore, OXC does not conform to the (+9, +7) positional shift pattern.

Explanation

To determine how many letters remain unchanged in their positions when the word VIRTUAL is arranged in English alphabetical order, we compare the original sequence of letters with the sorted sequence.

Original word: V I R T U A L

Alphabetical arrangement: A I L R T U V

Comparing the letter positions of both sequences: First position: V changes to A Second position: I remains I Third position: R changes to L Fourth position: T changes to R Fifth position: U changes to T Sixth position: A changes to U Seventh position: L changes to V

Only the letter I at the second position remains in its original place. Therefore, the position of only one letter remains unchanged.

Explanation

Each letter of the first group is shifted forward by 5 positions in the alphabetical order to obtain the corresponding letter of the second group. Additionally, the internal letters of each triad follow a +2, +1 positional spacing.

In the first set DFG : IKL: D + 5 = I F + 5 = K G + 5 = L Internal pattern: D (+2) → F (+1) → G, and I (+2) → K (+1) → L.

In the second set MOP : RTU: M + 5 = R O + 5 = T P + 5 = U Internal pattern: M (+2) → O (+1) → P, and R (+2) → T (+1) → U.

Following the same pattern, TVW : YAB matches perfectly: T + 5 = Y V + 5 = A W + 5 = B Internal pattern: T (+2) → V (+1) → W, and Y (+2) → A (+1) → B.

Explanation

An ordinary non-leap year consists of 365 days. To find the relation between the first day (January 1st) and the last day (December 31st) of the same year, we calculate the number of days that pass between them, which is 365 - 1 = 364 days.

Since there are 7 days in a week, we divide this duration by 7: 364 ÷ 7 = 52 weeks with a remainder of 0

A remainder of 0 indicates that December 31st falls on the exact same day of the week as January 1st. Thus, the first day and the last day of a non-leap year are always the same.

Explanation

In the expression T × X + Y + Z, the operators define the relationships between the individuals: T × X means T is the father of X. X + Y means X is the sibling (either brother or sister) of Y. Y + Z means Y is the sibling (either brother or sister) of Z.

Since X, Y, and Z are siblings sharing the same parents, and T is the father of X, T is also the father of Z.

Explanation

To find the code for the word "strong", we compare the two given sentences and their respective code representations.

The first sentence is "strong and mighty", which is coded as "ui yv tk". The second sentence is "soft yet strong", which is coded as "hd tk bw".

The only word common to both sentences is "strong". Correspondingly, the only code common to both code groups is "tk". Therefore, "strong" is coded as "tk".

Explanation

By interchanging '+' with '-' and '×' with '÷' in the mathematical expression, we get:

162 ÷ 9 + 452 - 7 × 9 = ?

Following the BODMAS rule:

First, perform the division: 162 ÷ 9 = 18

The expression becomes: 18 + 452 - 7 × 9

Next, perform the multiplication: 7 × 9 = 63

The expression becomes: 18 + 452 - 63

Next, perform the addition: 18 + 452 = 470

Finally, perform the subtraction: 470 - 63 = 407

Explanation

By substituting the combination of letters from option A (B, B, A, C, B, A, B) sequentially into the blanks, the series becomes: A B A B C A B A B C A B B A C A B A B C

This sequence can be divided into four groups of five letters each: Group 1: A B A B C Group 2: A B A B C Group 3: A B B A C Group 4: A B A B C

The series follows the repeating pattern of five-letter blocks of "A B A B C".

Explanation

By substituting the standard mathematical operators for the given letters, where U stands for ÷, D stands for ×, T stands for -, and B stands for +, the expression becomes:

13 - 26 ÷ 13 × 24 + 7

Following the BODMAS rule:

First, perform the division operation: 26 ÷ 13 = 2

The equation becomes: 13 - 2 × 24 + 7

Next, perform the multiplication operation: 2 × 24 = 48

The equation becomes: 13 - 48 + 7

Finally, perform the addition and subtraction operations: 13 + 7 - 48 = 20 - 48 = -28

Explanation

By comparing the letters in the words BEAM and MEAN, we find that the letters E, A, and M are common to both words. Similarly, comparing their respective codes 2349 and 4327, the common digits are 2, 3, and 4. This means that the letters E, A, and M correspond to the digits 2, 3, and 4 in some order. The only remaining letter in MEAN is N, and the only remaining digit in its code 4327 is 7. Therefore, the code for the letter N is 7.

Explanation

In the given sets (10, 5, 20) and (14, 7, 28), the relationship between the numbers (A, B, C) follows the pattern: B = A ÷ 2 C = A × 2

Applying this rule to the first set (10, 5, 20): 10 ÷ 2 = 5 10 × 2 = 20

Applying this rule to the second set (14, 7, 28): 14 ÷ 2 = 7 14 × 2 = 28

Applying the same logic to the set (22, 11, 44): 22 ÷ 2 = 11 22 × 2 = 44

Explanation

The relationship between the first number and the second number is given by dividing the first number by 6.

For the first pair: 96 ÷ 6 = 16

For the second pair: 156 ÷ 6 = 26

Applying this same relation to 228: 228 ÷ 6 = 38

Explanation

Each term in the series is obtained by applying a specific addition pattern to the positional values of the letters in the English alphabet:

For the first letter of each term, the positions are F (6), L (12), ?, X (24), D (4). The pattern is an addition of 6 to the previous letter position. Adding 6 to 12 (L) gives 18, which corresponds to the letter R.

For the second letter of each term, the positions are N (14), U (21), ?, I (9), P (16). The pattern is an addition of 7 to the previous letter position. Adding 7 to 21 (U) gives 28, which wraps around the alphabet (28 - 26) to 2, corresponding to the letter B.

For the third letter of each term, the positions are V (22), E (5), ?, W (23), F (6). The pattern is an addition of 9 to the previous letter position. Adding 9 to 5 (E) gives 14, which corresponds to the letter N.

Combining these letters yields the term RBN.

Explanation

Interchanging the numbers 52 and 39 in the given equation: 74 - 52 + (39 ÷ 13) × 16 + (14 ÷ 2) = 106

The modified equation becomes: 74 - 39 + (52 ÷ 13) × 16 + (14 ÷ 2) = 106

Applying the BODMAS rule, first solve the division terms inside the brackets: 52 ÷ 13 = 4 14 ÷ 2 = 7

This simplifies the equation to: 74 - 39 + 4 × 16 + 7 = 106

Next, perform the multiplication: 4 × 16 = 64

Now, substitute this back and perform addition and subtraction from left to right: 74 - 39 + 64 + 7 = 106 35 + 64 + 7 = 106 99 + 7 = 106 106 = 106

The Left Hand Side equals the Right Hand Side, making the equation correct.

Explanation

By decoding the operators where A represents division (÷), B represents multiplication (×), C represents addition (+), and D represents subtraction (-), the given equation can be rewritten as:

93 ÷ 3 + 15 × 5 - 12

Applying the BODMAS rule:

First, perform the division: 93 ÷ 3 = 31

Next, perform the multiplication: 15 × 5 = 75

The equation now becomes: 31 + 75 - 12

Now, perform the addition: 31 + 75 = 106

Finally, perform the subtraction: 106 - 12 = 94

Explanation

By comparing the two coded sentences, the common words and their corresponding codes can be identified. In the first sentence, "time and money" is coded as "zoo zee zig". In the second sentence, "time and tide" is coded as "zee zoo zaa".

The common words in both sentences are "time" and "and", and the common codes in both representations are "zoo" and "zee". Removing these common elements from the second sentence leaves the word "tide" and the code "zaa". Therefore, "tide" is the word coded as "zaa".

Explanation

To find the day of the week on 16 January 1967, we calculate the total number of odd days between 29 December 1956 and 16 January 1967.

First, we calculate the odd days for the 10-year period from 29 December 1956 to 29 December 1966. Within these 10 years, there are 2 leap years (1960 and 1964) and 8 ordinary years. Since a leap year has 2 odd days and an ordinary year has 1 odd day, the total odd days from the years is (2 × 2) + (8 × 1) = 12 odd days.

Next, we calculate the days from 29 December 1966 to 16 January 1967. There are 2 remaining days in December 1966 (30 and 31 December) and 16 days in January 1967, which gives a total of 18 days.

Adding these together, the total number of days is 12 + 18 = 30 days. Dividing 30 by 7 leaves a remainder of 2 odd days. Adding 2 odd days to Saturday results in Monday.

Explanation

By interchanging the mathematical signs where × and ÷ are interchanged, and + and - are interchanged, the given equation is rewritten as:

800 ÷ 16 + 8 × 12 - 18

According to the BODMAS rule, the operations are performed in the order of Division, Multiplication, Addition, and Subtraction:

First, division: 800 ÷ 16 = 50

Next, multiplication: 8 × 12 = 96

Finally, addition and subtraction: 50 + 96 - 18 = 146 - 18 = 128

Explanation

The given series follows the pattern where each subsequent number is obtained by multiplying the previous number by 2 and then subtracting 1.

The mathematical relation is: xₙ = 2xₙ₋₁ - 1

Applying this pattern to the terms of the series: 15 = 8 × 2 - 1 29 = 15 × 2 - 1 57 = 29 × 2 - 1 113 = 57 × 2 - 1

Following the same logic, the next term in the series is: 113 × 2 - 1 = 226 - 1 = 225

Explanation

Interchanging the signs where - and + are interchanged, and × and ÷ are interchanged, the original expression is rewritten.

Original expression: 73 - 27 × 9 + 5 ÷ 13

After interchanging the signs: 73 + 27 ÷ 9 - 5 × 13

Applying the BODMAS rule: First, perform the division: 27 ÷ 9 = 3

Next, perform the multiplication: 5 × 13 = 65

Now, perform the addition and subtraction: 73 + 3 - 65 = 76 - 65 = 11

Explanation

The logic behind the analogy is that the number of letters in each word is multiplied by 7. "MANGO" has 5 letters (5 x 7 = 35), "CHERRIES" has 8 letters (8 x 7 = 56), and "ADMINISTRATION" has 14 letters, which gives 14 x 7 = 98.

Explanation

The relation between the letter groups is based on their numerical positions in the English alphabetical order (A = 1, B = 2, ..., Z = 26).

The transformation from the source word to the target word follows these rules: The first letter of the target is obtained by adding 1 to the fourth letter of the source: Target[1] = Source[4] + 1 The second letter of the target is obtained by adding 9 to the second letter of the source: Target[2] = Source[2] + 9 The third letter of the target is obtained by adding 9 to the third letter of the source: Target[3] = Source[3] + 9 The fourth letter of the target is obtained by adding 1 to the first letter of the source: Target[4] = Source[1] + 1

Applying this logic to PCNZ (16, 3, 14, 26) to get ALWQ (1, 12, 23, 17): First letter: Z (26) + 1 = 27 → A (1) Second letter: C (3) + 9 = 12 → L Third letter: N (14) + 9 = 23 → W Fourth letter: P (16) + 1 = 17 → Q

Applying the same logic to HAXM (8, 1, 24, 13): First letter: M (13) + 1 = 14 → N Second letter: A (1) + 9 = 10 → J Third letter: X (24) + 9 = 33 → 7 (since 33 - 26 = 7) → G Fourth letter: H (8) + 1 = 9 → I

Thus, HAXM relates to NJGI.

Explanation

The coding pattern multiplies the positional value of each letter in the English alphabet by 2.

For GCJL: G = 7 → 7 × 2 = 14 C = 3 → 3 × 2 = 6 J = 10 → 10 × 2 = 20 L = 12 → 12 × 2 = 24

For WTRO: W = 23 → 23 × 2 = 46 T = 20 → 20 × 2 = 40 R = 18 → 18 × 2 = 36 O = 15 → 15 × 2 = 30

Applying the same pattern to BZKQ: B = 2 → 2 × 2 = 4 Z = 26 → 26 × 2 = 52 K = 11 → 11 × 2 = 22 Q = 17 → 17 × 2 = 34

The resulting code is 4-52-22-34.

Explanation

The number of years between 26 September 2005 and 26 September 2017 is 12 years.

During this period, there are 3 leap years (2008, 2012, and 2016) and 9 ordinary years.

Since an ordinary year has 1 odd day and a leap year has 2 odd days, the total number of odd days is calculated as: Total odd days = (9 × 1) + (3 × 2) = 15 odd days

To find the net odd days, we divide 15 by 7, which gives a remainder of 1.

Adding 1 odd day to Monday gives Tuesday.

Explanation

The relationship between the numbers in each set (A, B, C) is defined by the following pattern:

A = 3 × B B = 5 × C

Let us verify this logic with the given sets:

For the set (45, 15, 3): 15 × 3 = 45 3 × 5 = 15

For the set (120, 40, 8): 40 × 3 = 120 8 × 5 = 40

Applying this same logic to the set (165, 55, 11): 55 × 3 = 165 11 × 5 = 55

Explanation

Each letter cluster in the group follows a specific positional difference pattern where the second letter is obtained by adding 6 to the first letter, and the third letter is obtained by adding 7 to the second letter in alphabetical order.

In TZD, the position of T is 20, Z is 26, and D is 4. The difference between T and Z is +6, but the difference between Z and D is only +4 (since 26 + 4 = 30, which corresponds to D). Because it follows a (+6, +4) positional pattern instead of (+6, +7), it does not belong to the group.

Explanation

The relationship between the numbers is based on adding a constant value of 111 to the first number to obtain the second number.

For the first pair, the difference is: 876 - 765 = 111

For the second pair, the difference is: 793 - 682 = 111

Applying this same logic to the number 587: 587 + 111 = 698

Explanation

In the expression M - N × O, the relationships are decoded from left to right: M - N indicates that M is the wife of N, which makes N the husband of M. N × O indicates that N is the father of O. Since N is the father of O and M is married to N as his wife, M must be the mother of O.

Explanation

The statement All chairs are sofas means the set of chairs is entirely contained within the set of sofas. The statement No sofa is a table indicates that the set of sofas and the set of tables have no elements in common. Since all chairs are inside the set of sofas, it is impossible for any chair to be a table. This makes conclusion II, No table is a chair, logically true.

The statement Some chairs are beds means there is a common intersection between the set of chairs and the set of beds. Since the entire set of chairs is contained within the set of sofas, any element that is shared between chairs and beds must also be a part of the set of sofas. This guarantees a common intersection between sofas and beds, making conclusion III, Some sofas are beds, logically true.

Explanation

The series follows a pattern where each letter in a term is shifted forward by 10 positions in the alphabetical order to obtain the corresponding letter of the next term.

For the first letter of each term: Q (17) + 10 = A (27 or 1) A (1) + 10 = K (11) K (11) + 10 = U (21) U (21) + 10 = E (31 or 5)

For the second letter of each term: J (10) + 10 = T (20) T (20) + 10 = D (30 or 4) D (4) + 10 = N (14) N (14) + 10 = X (24)

For the third letter of each term: C (3) + 10 = M (13) M (13) + 10 = W (23) W (23) + 10 = G (33 or 7) G (7) + 10 = Q (17)

Combining these letters yields EXQ.

Explanation

The series follows a pattern where each subsequent term is obtained by multiplying the previous term by 2 and subtracting 10.

Using the relation Tₙ = 2 × Tₙ₋₁ - 10: 34 × 2 - 10 = 58 58 × 2 - 10 = 106 106 × 2 - 10 = 202 202 × 2 - 10 = 394

Applying the same logic to find the next term: 394 × 2 - 10 = 778

Alternatively, the differences between consecutive terms double at each step: 58 - 34 = 24 106 - 58 = 48 202 - 106 = 96 394 - 202 = 192

The next difference must be 192 × 2 = 384. Adding this to the last term gives 394 + 384 = 778.

Explanation

Each term in the series is determined by applying a specific subtraction pattern to the alphabetical positions of its letters:

The first letters decrease by 3 positions in each step: F (6) minus 3 is C (3); C (3) minus 3 is Z (26); Z (26) minus 3 is W (23); W (23) minus 3 is T (20).

The second letters decrease by 5 positions in each step: Q (17) minus 5 is L (12); L (12) minus 5 is G (7); G (7) minus 5 is B (2); B (2) minus 5 is W (23, since rolling back from B goes through A to Z, Y, X, W).

The third letters decrease by 2 positions in each step: N (14) minus 2 is L (12); L (12) minus 2 is J (10); J (10) minus 2 is H (8); H (8) minus 2 is F (6).

Combining these results gives the next group as TWF.

Explanation

Combining the second statement, all onions are potatoes, and the third statement, all potatoes are radish, we use transitivity to establish that all onions are radish. This validates conclusion II.

Combining the first statement, some carrots are onions, with the second statement, all onions are potatoes, reveals that some carrots are potatoes. Further combining this with the third statement, all potatoes are radish, confirms that the intersecting group of carrots and potatoes must also be radish. This validates conclusion I.

Explanation

The series follows a specific mathematical pattern for each position of the letters:

For the first letter, the positions are B (2), F (6), J (10), and N (14). The pattern is adding 4 to the position of each preceding letter. The next letter is 14 + 4 = 18, which corresponds to R.

For the second letter, the positions are O (15), Q (17), S (19), and U (21). The pattern is adding 2 to the position of each preceding letter. The next letter is 21 + 2 = 23, which corresponds to W.

For the third letter, the positions are J (10), O (15), and T (20). The pattern is adding 5 to the position of each preceding letter. Continuing this consistent addition of 5, the fourth term's last letter corresponds to Y (25), and the next letter in the sequence is 25 + 5 = 30. Since there are 26 letters in the alphabet, 30 corresponds to 30 - 26 = 4, which is D.

Combining these letters yields the term RWD.

Explanation

By decoding the symbols in the expression A@B | C@D+K÷F, the relations between the individuals are determined step-by-step:

C @ D means C is the father of D.

D + K means D is the sister of K.

Since D is the sister of K, they are siblings sharing the same parents. Because C is the father of D, C is also the father of K.

Explanation

The given series is 3, 9, 21, 41, 71, X.

To find the pattern, calculate the differences between consecutive terms: 9 - 3 = 6 21 - 9 = 12 41 - 21 = 20 71 - 41 = 30

The first-level differences are 6, 12, 20, and 30. These differences follow a pattern of consecutive products of two consecutive integers: 2 × 3 = 6 3 × 4 = 12 4 × 5 = 20 5 × 6 = 30

Following this pattern, the next difference in the series must be: 6 × 7 = 42

Adding this difference to the last term of the series gives the value of X: 71 + 42 = 113

Explanation

The coding pattern multiplies the sum of the alphabetical positions of the letters in the word by 2.

Using the standard alphabetical positions where A = 1, B = 2, C = 3, and so on:

For BABE: Sum of positions = 2 + 1 + 2 + 5 = 10 Code = 10 × 2 = 20

For EACH: Sum of positions = 5 + 1 + 3 + 8 = 17 Code = 17 × 2 = 34

Applying this to FACT: Sum of positions = 6 + 1 + 3 + 20 = 30 Code = 30 × 2 = 60

Explanation

To find the day of the week on 8 October 2015 starting from 10 October 2003, we first calculate the total number of odd days between 10 October 2003 and 10 October 2015.

The total number of years is 2015 - 2003 = 12 years.

Among these 12 years, the leap years containing 29 February are 2004, 2008, and 2012, which gives 3 leap years. The remaining 9 years are ordinary years.

Using the standard calendar relation for odd days: Total odd days = (9 × 1) + (3 × 2) = 15 odd days.

Dividing 15 by 7 to find the net odd days: 15 mod 7 = 1 odd day.

This means 10 October 2015 is 1 day ahead of 10 October 2003 (Friday), which makes it a Saturday.

To find the day on 8 October 2015, we subtract 2 days from Saturday, which gives Thursday.

Explanation

The numbers in each set follow the pattern (a, b, c) where the second number is the square of the first number (b = a²), and the third number is twice the second number (c = 2 × b).

Applying this pattern to the given sets: For (4, 16, 32): 16 = 4² 32 = 2 × 16

For (7, 49, 98): 49 = 7² 98 = 2 × 49

Applying the same logic to the correct set (12, 144, 288): 144 = 12² 288 = 2 × 144

Explanation

The given series is an arithmetic progression where each subsequent term is obtained by subtracting a constant value from the preceding term. By calculating the difference between consecutive terms:

244 - 232.1 = 11.9 232.1 - 220.2 = 11.9 220.2 - 208.3 = 11.9 208.3 - 196.4 = 11.9

Since the common difference is -11.9, the next term in the series is calculated by subtracting 11.9 from the last given term:

196.4 - 11.9 = 184.5

Explanation

By comparing the words RISK and KIRT, the common letters in both words are R, I, and K. Correspondingly, the common digits in their codes 3921 and 1693 are 3, 9, and 1. The letter S is present in RISK but not in KIRT, which means its code must be the digit present in 3921 but not in 1693. This unique digit is 2, which represents the code for S.

Explanation

In the expression K = R + M:

K = R indicates that K is the sister of R. R + M indicates that R is the son of M.

Since K is the sister of R and R is the son of M, K must be the daughter of M.

Explanation

By interchanging the signs as specified:

• is interchanged with - (+ becomes - and - becomes +) × is interchanged with ÷ (× becomes ÷ and ÷ becomes ×)

Applying these changes to the equation: 59 - 39 + 63 ÷ 21 × 26 = ?

According to the BODMAS rule, perform the operations in the order of Division, Multiplication, Addition, and Subtraction:

First, perform division: 63 ÷ 21 = 3

Next, perform multiplication: 3 × 26 = 78

Now, perform addition and subtraction: 59 - 39 + 78 = 20 + 78 = 98

Explanation

The relationship between the numbers follows a simple multiplication pattern where the second number is obtained by multiplying the first number by 3.

129 × 3 = 387

164 × 3 = 492

Following the same logic, the number related to 148 is:

148 × 3 = 444

Explanation

By decoding the letter symbols to their respective mathematical operators: J stands for division (÷) K stands for addition (+) A stands for subtraction (-) V stands for multiplication (×)

Substituting these operators into the given equation: 12 ÷ 2 + 17 - 15 × 19

Applying the BODMAS rule: First, perform division and multiplication: 12 ÷ 2 = 6 15 × 19 = 285

This simplifies the expression to: 6 + 17 - 285

Next, perform addition: 6 + 17 = 23

Finally, perform subtraction: 23 - 285 = -262

Explanation

The series is formed by repeating the 11-letter pattern: F E G E F E F E G E E.

By dividing the given series into two parts, we get: First part: F _ G E _ E _ E _ E E Second part: F _ G E _ E _ E G

Substituting the letters from the option D (E, F, F, G, E, F, F) into the blanks sequentially completes the pattern: First part: F [E] G E [F] E [F] E [G] E E Second part: F [E] G E [F] E [F] E G (truncated at G)

This completes the repeating pattern F E G E F E F E G E E.
