SSC CHSL Tier 1 2016 General Intelligence & Reasoning Questions with Solutions

Explanation

The series is formed by two independent patterns for the first and second letters of each term.

For the first letter, the sequence is N, P, S, ... The alphabetical positions of these letters are N = 14, P = 16, and S = 19. The difference between consecutive positions increases by 1 each time: 14 + 2 = 16 (P) 16 + 3 = 19 (S) Following this pattern, the next position is 19 + 4 = 23, which corresponds to the letter W.

For the second letter, the sequence is M, K, I, ... The alphabetical positions of these letters are M = 13, K = 11, and I = 9. The pattern shows a constant decrease of 2: 13 - 2 = 11 (K) 11 - 2 = 9 (I) Following this pattern, the next position is 9 - 2 = 7, which corresponds to the letter G.

Combining the first and second letters gives the term WG.

Explanation

The given series progresses by multiplying each consecutive term with an increasing sequence of integers starting from 5.

The pattern of multiplication is: 1 × 5 = 5 5 × 6 = 30 30 × 7 = 210 210 × 8 = 1680

Following this pattern, the next term is obtained by multiplying the fifth term by 9: 1680 × 9 = 15120

Explanation

The given statements are: 1 < 2 2 < 3

Combining these two inequalities using the transitive property of inequality gives the relation: 1 < 2 < 3

From this relation, it directly follows that 1 < 3. Therefore, Conclusion I is logically valid and follows from the statements.

Conclusion II is 2 < 3, which is identical to the second statement. In logical deduction, any statement that is directly given as a true premise is also a valid conclusion. Thus, Conclusion II also follows.

Explanation

Let Rohit's age be R and Ankit's age be A.

Based on the given information, we can set up the following equations: R + A = 78 R = 2A

Substituting R = 2A into the first equation: 2A + A = 78 3A = 78 A = 26

Using the value of A to find Rohit's age: R = 2 × 26 = 52

Explanation

To arrange the words in alphabetical order, compare them letter by letter from left to right. All four words start with the common prefix Trans.

Comparing the sixth letters of each word: Transistor has i. Translucent has l. Transparent and Transport both have p.

Since i comes before l, and l comes before p in the alphabet, Transistor (iv) is the first word, followed by Translucent (i).

To determine the order between the remaining two words, Transparent (ii) and Transport (iii), compare their seventh letters. Transparent has a while Transport has o. Since a comes before o, Transparent (ii) precedes Transport (iii).

Explanation

The coding pattern follows an increasing sequence of addition to the alphabetical positions of each letter in the word, starting from 0.

By mapping the letters of INSTANT to their positions in the alphabet: I (9) + 0 = I (9) N (14) + 1 = O (15) S (19) + 2 = U (21) T (20) + 3 = W (23) A (1) + 4 = E (5) N (14) + 5 = S (19) T (20) + 6 = Z (26)

Applying the same pattern of +0, +1, +2, +3, +4, +5 to the word FORGET: F (6) + 0 = F (6) O (15) + 1 = P (16) R (18) + 2 = T (20) G (7) + 3 = J (10) E (5) + 4 = I (9) T (20) + 5 = Y (25)

Explanation

The pattern in each column of the matrix is obtained by multiplying the number in the second row with the number in the third row to get the number in the first row.

In the second column, multiplying the numbers gives: 11 × 18 = 198

In the third column, multiplying the numbers gives: 12 × 10 = 120

Following this same rule for the first column, we multiply the numbers in the second and third rows: 9 × 4 = 36

Explanation

Substituting the given operations in place of the letters: 187 B 17 C 4 A 7 D 17 = 187 ÷ 17 × 4 + 7 - 17

According to the BODMAS rule, perform division first: 187 ÷ 17 = 11

Now the expression is: 11 × 4 + 7 - 17

Next, perform multiplication: 11 × 4 = 44

Now the expression is: 44 + 7 - 17

Next, perform addition and then subtraction: 44 + 7 = 51 51 - 17 = 34

Explanation

The series is composed of 12 letters, which can be divided into three groups of four letters each: l_n_, o_m_, and lm_o. Placing the letters m, o, n, l, n sequentially in the blanks completes the series as follows:

l m n o | o n m l | l m n o

This reveals a clear alternating and symmetric pattern where the first group of four letters (l m n o) is in forward alphabetical order, the second group of four letters (o n m l) is in reverse alphabetical order, and the third group (l m n o) returns to the forward order. Thus, the letters to fill the gaps are m, o, n, l, n.

Explanation

The boy's movement forms a right-angled triangle where the starting point, the point of turning, and the final destination are the vertices.

The distance from the starting position is the hypotenuse of this right-angled triangle, calculated directly using the Pythagorean theorem:

Distance = √(4² + 3²) = √(16 + 9) = √25 = 5 km

Initially, the boy travels south. Turning right while facing south directs him towards the west. Since he has moved south and then west, his final position relative to his starting point is in the south-west direction.

Explanation

The word TEST is represented by the codes 76, 44, 23, and 11 based on the row and column identification from the matrices.

The first letter T is represented by 76, where row 7 and column 6 in Matrix-II intersect at T.

The second letter E is represented by 44, where row 4 and column 4 in Matrix-I intersect at E.

The third letter S is represented by 23, where row 2 and column 3 in Matrix-I intersect at S.

The fourth letter T is represented by 11, where row 1 and column 1 in Matrix-I intersect at T.

Explanation

Let Rajesh's father-in-law be F. Since Rajesh is married to F's daughter, F is the father of Rajesh's wife. Rajesh's wife has a younger sister, who is also F's daughter. Kishan is the son-in-law of F. Since Rajesh is already married to one daughter of F, Kishan is married to the other daughter (the younger sister of Rajesh's wife). Because Rajesh and Kishan are married to two sisters, they are brothers-in-law to each other. Therefore, Rajesh is the brother-in-law of Kishan.

Explanation

The relationship between the first pair of words is antonymous, where opposite is the direct antonym of identical. Following the same analogy, the antonym of lengthy is short.

Explanation

The relationship between the letters in each pair is determined by shifting the alphabetical position of each letter forward by 2.

In the first pair, GT : IV: The position of G is 7, and adding 2 gives 9, which is the letter I. The position of T is 20, and adding 2 gives 22, which is the letter V.

Applying this same logic to KX: The position of K is 11, and adding 2 gives 13, which is the letter M. The position of X is 24, and adding 2 gives 26, which is the letter Z.

Explanation

The letters in the second group are the reverse positional equivalents of the letters in the first group in alphabetical order, where the sum of their numerical positions from the start and the end of the alphabet is 27.

The position of B is 2, and the 2nd letter from the end is Y. The position of C is 3, and the 3rd letter from the end is X. The position of D is 4, and the 4th letter from the end is W.

Applying this pattern to FGH: The position of F is 6, and the 6th letter from the end is U. The position of G is 7, and the 7th letter from the end is T. The position of H is 8, and the 8th letter from the end is S.

Explanation

The relationship between the numbers is based on the product of the digits of the first number.

For the first pair, the product of the digits of 66 is: 6 × 6 = 36

Applying the same logic to the second pair, the product of the digits of 99 is: 9 × 9 = 81

Explanation

The fox belongs to the canine family (Canidae), whereas the other animals belong to the feline family (Felidae), making it the odd one out.

Explanation

The letter group MNO is written in consecutive forward alphabetical order, where M is the 13th letter, N is the 14th letter, and O is the 15th letter. This differs from the pattern of the other groups which are written in reverse alphabetical order.

Explanation

The relationship between the numbers in each pair follows the pattern where the second number is obtained by squaring the first number and adding 1.

Using the formula y = x² + 1:

For the first pair, when x = 7: y = 7² + 1 = 49 + 1 = 50

Following the same logic for the second pair, when x = 9: y = 9² + 1 = 81 + 1 = 82

Explanation

The relationship between the numbers is based on taking the first digit of the number and raising it to the power of the second digit.

For the first pair, 23 is processed as 2³ = 8.

Applying the same logic to the second pair, 62 is processed as 6² = 36.

Explanation

The given series represents units of mass arranged in ascending order, where each successive unit is 1000 (10³) times larger than the preceding one.

1 nanogram = 10⁻⁹ grams 1 microgram = 10⁻⁶ grams 1 milligram = 10⁻³ grams 1 gram = 1 gram

Following this progression, the unit that is 1000 times smaller than a microgram and completes the series is the nanogram.

Explanation

The number of letters in each term increases by 1 with each step: BC has 2 letters, GHI has 3 letters, and NOPQ has 4 letters. Thus, the missing term must contain 5 consecutive letters.

The alphabetical gap between the terms increases progressively. The difference between the last letter of the first term (C, position 3) and the first letter of the second term (G, position 7) is 7 - 3 = 4. The difference between the last letter of the second term (I, position 9) and the first letter of the third term (N, position 14) is 14 - 9 = 5. Following this pattern, the difference between the last letter of the third term (Q, position 17) and the first letter of the missing term must be 5 + 1 = 6.

Adding 6 to the position of Q (17 + 6 = 23) gives the letter W. Writing 5 consecutive letters starting from W yields W, X, Y, Z, and A.

Explanation

Each term in the series follows a specific alphabetical position shift.

For the first letter of each term: D (position 4) to B (position 2) is a decrease of 2. B (position 2) to Y (position 25) is a decrease of 3, by counting backward. Following this pattern, the next change is a decrease of 4. Y (position 25) minus 4 gives position 21, which is U.

For the second letter of each term: E (position 5) to G (position 7) is an increase of 2. G (position 7) to J (position 10) is an increase of 3. Following this pattern, the next change is an increase of 4. J (position 10) plus 4 gives position 14, which is N.

Combining these letters yields UN.

Explanation

The relationship in the analogy is between an animal and its young offspring. A young horse is called a foal, and in the same way, the young one of a swan is called a cygnet.

Explanation

Since some crows are jackals and no fox is a crow, the jackals that are crows can never be foxes. Therefore, the conclusion that some jackals are not foxes definitely follows, while the conclusion that some jackals are foxes is not necessarily true.

Explanation

The terms of the series follow the pattern of adding the term position number to its cube, represented by the formula n³ + n for the n-th term.

For the first term (n = 1): 1³ + 1 = 1 + 1 = 2 For the second term (n = 2): 2³ + 2 = 8 + 2 = 10 For the third term (n = 3): 3³ + 3 = 27 + 3 = 30 For the fourth term (n = 4): 4³ + 4 = 64 + 4 = 68

Applying the same pattern for the fifth term (n = 5): 5³ + 5 = 125 + 5 = 130

Explanation

Let the present age of Rajan be R and the age of his son be S.

The sum of their ages is calculated from their average age: R + S = 20 × 2 = 40

Since Rajan's present age is three times his son's age: R = 3S

Substituting R = 3S into the sum equation gives: 3S + S = 40 4S = 40 S = 10

The present age of Rajan is: R = 3 × 10 = 30 years

Rajan's age 5 years from now will be: 30 + 5 = 35 years

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right.

All four words begin with the letter N.

Comparing the second letters, Nocking, Nonjury, and Nozzle have the letter o, while Nuzzled has the letter u. Since o comes before u, Nuzzled is placed last in the sequence.

Next, we compare the third letters of the three words starting with No: In Nocking, the third letter is c. In Nonjury, the third letter is n. In Nozzle, the third letter is z.

Since c comes before n, and n comes before z in the alphabet, the alphabetical order of these three words is Nocking, Nonjury, and Nozzle. Combining this with Nuzzled gives the final dictionary sequence: iv, iii, ii, i.

Explanation

The word BISLERI is divided into two parts: the first four letters (BISL) and the last three letters (ERI). The coded word IREBISL is formed by reversing the last three letters to get IRE, and then appending the first four letters BISL unchanged.

Applying the same pattern to the word PANTHER, the first four letters are PANT and the last three letters are HER. Reversing the last three letters gives REH, and appending the first four letters unchanged gives REHPANT.

Explanation

The pattern in each row is that the third number is obtained by raising the first number to the power of the second number.

In the first row, 7² = 49. In the second row, 8³ = 512. In the third row, the relationship is 11 raised to the power of the missing number equals 1331. Since 11³ = 1331, the missing number is 3.

Explanation

Replacing the letters with their respective mathematical operators: V represents subtraction (-) M represents addition (+) L represents division (÷) S represents multiplication (×)

The given expression is: 7 V 42 M 56 L 8 S 5

Substituting the operators: 7 - 42 + 56 ÷ 8 × 5

According to the BODMAS rule, the operations must be performed in the order of Division, Multiplication, Addition, and Subtraction.

First, perform the division operation: 56 ÷ 8 = 7

The expression becomes: 7 - 42 + 7 × 5

Next, perform the multiplication operation: 7 × 5 = 35

The expression becomes: 7 - 42 + 35

Finally, perform the addition and subtraction from left to right: 7 - 42 + 35 = -35 + 35 = 0

Explanation

The given letter series with blanks is J _ J _ L _ K L _ J K _ M N.

The series follows an increasing sequential pattern where each successive group of letters starts with J and increases in length by one letter:

Group 1: J K Group 2: J K L Group 3: J K L M Group 4: J K L M N

Combining these groups sequentially forms the complete series: J K J K L J K L M J K L M N

By comparing this with the original series, the letters required to fill the blanks in order are: First blank: K Second blank: K Third blank: J Fourth blank: M Fifth blank: L

The sequential set of letters that completes the gaps is KKJML.

Explanation

Let the initial position of A be the origin (0, 0).

Traveling 12 km towards north brings A to the coordinates (0, 12).

Turning left means A now faces west. Traveling 5 km west brings him to the position (-5, 12).

From here, turning 180° anticlockwise means A reverses direction to face east. Traveling 10 km east from (-5, 12) moves him along the x-axis to the coordinates (5, 12), because -5 + 10 = 5.

The minimum distance d between the initial position (0, 0) and the final position (5, 12) is calculated using the distance formula:

d = √(5² + 12²) = √(25 + 144) = √169 = 13 km.

Explanation

Each character of the word TEMP is represented by its row index followed by its column index from the respective matrices.

For the letter T, Row 5 and Column 5 of Matrix-II intersect at the letter T, representing it as 55.

For the letter E, Row 2 and Column 3 of Matrix-I intersect at the letter E, representing it as 23.

For the letter M, Row 7 and Column 8 of Matrix-II intersect at the letter M, representing it as 78.

For the letter P, Row 4 and Column 4 of Matrix-I intersect at the letter P, representing it as 44.

This gives the complete numeric set 55, 23, 78, 44 for the word TEMP.

Explanation

The relationship between the letter groups is determined by the alphabetical positions of the letters, where A = 1, B = 2, C = 3, and so on.

For the first pair, the letters ABCD and MOQS are represented by their positional values: A = 1, B = 2, C = 3, D = 4 M = 13, O = 15, Q = 17, S = 19

The pattern of transformation is established by adding consecutive integers starting from 12 to each letter of the first group: 1 + 12 = 13 (M) 2 + 13 = 15 (O) 3 + 14 = 17 (Q) 4 + 15 = 19 (S)

Applying this same logic to the letter group FGHI: F = 6, G = 7, H = 8, I = 9

By adding the corresponding increments: 6 + 12 = 18 (R) 7 + 13 = 20 (T) 8 + 14 = 22 (V) 9 + 15 = 24 (X)

This yields the sequence RTVX.

Explanation

Raju's wife's sister is his sister-in-law. The son of one's sister-in-law is defined as a nephew. Thus, the boy is Raju's nephew.

Explanation

In the alphabetical series, the relationship between the first two terms BY and GT is established by shifting the position of the letters.

The first letter B (2nd position) is shifted forward by 5 positions to get G (7th position). The second letter Y (25th position) is shifted backward by 5 positions to get T (20th position).

Applying the same logic to the third term DW: The first letter D (4th position) is shifted forward by 5 positions to get I (9th position). The second letter W (23rd position) is shifted backward by 5 positions to get R (18th position).

Additionally, the letters in each pair are alphabetical opposites whose position values sum to 27: B (2) + Y (25) = 27 G (7) + T (20) = 27 D (4) + W (23) = 27 I (9) + R (18) = 27

Explanation

The relationship between the first pair of numbers is based on a simple ratio of 2:3.

By simplifying the ratio of 12:18, we divide both numbers by their greatest common divisor, 6, which yields 2:3.

Applying the same ratio to the second pair, we set up the proportion:

80 : x = 2 : 3

To find x, we multiply 80 by 3/2:

x = 80 × (3/2) = 40 × 3 = 120

Explanation

Iraq is a country, unlike the other terms which represent units of currency.

Explanation

The letter G is a consonant, whereas all the other options are vowels.

Explanation

The sum of the digits of 581 is 5 + 8 + 1 = 14, whereas the sum of the digits of the other numbers is 17.

Explanation

The numbers 126, 168, and 224 are completely divisible by 7, whereas 240 is not divisible by 7:

126 ÷ 7 = 18 168 ÷ 7 = 24 224 ÷ 7 = 32 240 ÷ 7 = 34.28...

Explanation

The given sequence is an alternating series consisting of two separate sub-series.

The first sub-series is formed by the odd-positioned terms: B, F, J, N, and the first missing term. Translating these letters to their alphabetical positions yields 2, 6, 10, and 14. This sub-series increases by a constant difference of +4. Following this pattern, the next term is 14 + 4 = 18, which corresponds to the letter R.

The second sub-series is formed by the even-positioned terms: C, E, G, I, and the second missing term. Translating these letters to their alphabetical positions yields 3, 5, 7, and 9. This sub-series increases by a constant difference of +2. Following this pattern, the next term is 9 + 2 = 11, which corresponds to the letter K.

Explanation

The relationship in the first pair is that of a finished product to its primary raw material, as an omelette is made from egg. Similarly, cloth is manufactured from fibre, which serves as its primary raw material.

Explanation

Look at the three letters in each group separately. The first letters go E, H, K, so the next one is N (each jumps ahead by three places). The second letters go L, N, P, so the next is R (each jumps ahead by two places). The third letters go P, S, V, so the next is Y (each jumps ahead by three places). Putting these together gives NRY as the missing term.

Explanation

The logic of the analogy lies in the relationship between the positions of letters from both ends of the English alphabet. For any letter, its corresponding opposite letter is found at the same position from the reverse end of the alphabet, where the sum of their numerical positions equals 27.

For the first pair JK : PQ: The opposite letter of J (10th) is Q (17th, since 10 + 17 = 27). The opposite letter of K (11th) is P (16th, since 11 + 16 = 27). Reversing the order of these opposite letters (QP) results in PQ.

Applying the same pattern to FG: The opposite letter of F (6th) is U (21st, since 6 + 21 = 27). The opposite letter of G (7th) is T (20th, since 7 + 20 = 27). Reversing the order of these opposite letters (UT) results in TU.

Explanation

There is a constant positional shift between the corresponding letters in the analogy:

Using the relationship between the first and third terms: For the first letters (uppercase): T (20) + 9 = 29 ≡ 3 (C) (modulo 26) Applying this to the first letter of the second term: A (1) + 9 = 10 (J)

For the second letters (lowercase): u (21) + 9 = 30 ≡ 4 (d) (modulo 26) Applying this to the second letter of the second term: b (2) + 9 = 11 (k)

Alternatively, looking at the relationship between the first and second terms: T (20) - 19 = A (1) u (21) - 19 = b (2)

Applying this same subtraction of 19 positions to the third term: C (3) - 19 = -16 ≡ 10 (J) (modulo 26) d (4) - 19 = -15 ≡ 11 (k) (modulo 26)

Following the letter case pattern of uppercase followed by lowercase, we get Jk.

Explanation

The relationship between the first two numbers follows the pattern n × (n + 1).

For the first term, 7 × (7 + 1) = 7 × 8 = 56.

Applying the same pattern to the second term, we get: 9 × (9 + 1) = 9 × 10 = 90.

Explanation

Deceit represents the act of deceiving, dishonesty, or misrepresenting the truth. The other words in the group all share a common theme of truthfulness, integrity, and authenticity, making deceit the antonym and the odd word among them.

Explanation

The letter group TBC consists entirely of consonants and does not contain any vowels, unlike the other letter groups which each contain a vowel.
