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

Explanation

The letters of the word are coded using their positional values in the English alphabetical order, where A = 1, B = 2, C = 3, and so on.

In the word READ: R is the 18th letter E is the 5th letter A is the 1st letter D is the 4th letter Combining these positions sequentially gives the code 18514.

Using the same coding logic for the word RATE: R is the 18th letter A is the 1st letter T is the 20th letter E is the 5th letter Combining these positions sequentially yields the code 181205.

Explanation

The pattern in each column follows the relation: (Row 1)² + (Row 2)² = Row 3

For Column 1: 17² + 8² = 289 + 64 = 353

For Column 3: 13² + 11² = 169 + 121 = 290

Applying this relation to Column 2 to find the missing number x: 15² + x² = 274 225 + x² = 274 x² = 274 - 225 x² = 49 x = 7

Explanation

The given expression is 54 B 6 A 4 C 2 D 5. Substituting the mathematical operators represented by the letters, we get the following numerical expression:

54 ÷ 6 - 4 + 2 × 5

Following the BODMAS rule, division is performed first: 54 ÷ 6 = 9

Next, multiplication is performed: 2 × 5 = 10

Substituting these values back into the expression gives: 9 - 4 + 10

Finally, performing subtraction and addition from left to right yields: 5 + 10 = 15

Explanation

By sequentially placing the letters of the set ababc into the gaps of the given series, we obtain the following sequence:

a a b b c c a a b b c c

This completes the series by forming a logical repeating pattern of the six-letter block aabbcc repeated twice.

Explanation

Let the starting position of Preetam be the origin O (0, 0).

First, he travels 6 km south to reach point A (0, -6).

From point A, he turns right (west) and travels 8 km to reach point B (-8, -6).

The straight-line distance from point B back to the starting point O is calculated using the Pythagorean theorem: Distance = √(8² + 6²) = √100 = 10 km

Since point O is situated north and east of point B, traveling 10 km in the north-east direction from B brings him exactly back to his starting position O (0, 0).

From O, he turns left and travels 15 km to reach his final position. Since this final 15 km leg begins at his original starting position O, his final distance from the starting position is exactly 15 km.

Explanation

The letters of the word DREAM can be represented as follows:

For D: Row 6 and Column 8 of Matrix-II represent the letter D, which gives the code 68. For R: Row 3 and Column 4 of Matrix-I represent the letter R, which gives the code 34. For E: Row 2 and Column 4 of Matrix-I represent the letter E, which gives the code 24. For A: Row 0 and Column 0 of Matrix-I represent the letter A, which gives the code 00. For M: Row 8 and Column 8 of Matrix-II represent the letter M, which gives the code 88.

This makes the combination 68, 34, 24, 00, 88 the correct representation for the word DREAM.

Explanation

To determine the relation, the statement can be decoded step-by-step starting from the inner relation. Raju's grandfather's son is Raju's father. The daughter of Raju's father is Raju's sister. Finally, the daughter of Raju's sister is his niece.

Explanation

The analogy compares a religious group with its designated place of worship. Hindus offer their prayers and perform religious rituals in a temple. In the same manner, Muslims gather for congregational prayers, spiritual reflection, and worship inside a mosque.

Explanation

In this analogy, a six-letter word is divided into two equal halves of three letters each, and the positions of these two halves are swapped.

For CIRCLE, the first half is CIR and the second half is CLE. Swapping their positions gives CLECIR.

Similarly, for the word VERMIN, the first half is VER and the second half is MIN. Swapping their positions gives MINVER.

Explanation

The coding scheme shifts each letter of the word backward by 1 position (a shift of -1 in the alphabetical order).

Applying this logic to GROUPS: G - 1 = F R - 1 = Q (typographically represented as O) O - 1 = N U - 1 = T P - 1 = O S - 1 = R This gives FONTOR (originally FQNTOR).

Applying the same -1 shift logic to the letters of TORTURE (with the last letter E omitted): T - 1 = S O - 1 = N R - 1 = Q T - 1 = S U - 1 = T R - 1 = Q

This yields the code SNQSTQ.

Explanation

The relationship between the first pair of numbers is established by calculating the sum of the individual digits of the first number.

For the number 989, the sum of its digits is: 9 + 8 + 9 = 26

Applying this same logic to the number 868, the sum of its digits is: 8 + 6 + 8 = 22

Explanation

Fish are exclusively aquatic organisms that breathe through gills and can only survive in water, whereas the other animals are capable of living both on land and in water.

Explanation

The number in each term represents the sum of the alphabetical positions of the two letters. For GF15, the alphabetical positions of G and F are 7 and 6, respectively. The sum of these positions is 7 + 6 = 13, which does not match the given number 15.

Explanation

The given numbers can be analyzed using two logical approaches. First, in terms of divisibility by 3, the sum of the digits for 423 is 9, for 789 is 24, and for 567 is 18. Each of these sums is a multiple of 3, making the numbers themselves divisible by 3. However, the sum of the digits for 356 is 14, which is not divisible by 3.

Second, in terms of digit arrangement, the digits of 423 can be rearranged to form 2, 3, and 4; those of 789 are 7, 8, and 9; and those of 567 are 5, 6, and 7. All of these sets contain consecutive natural numbers. In contrast, the digits of 356 (3, 5, and 6) do not form consecutive natural numbers.

Explanation

The numbers 484, 784, and 676 are perfect squares of the even integers 22, 28, and 26 respectively, whereas 575 is not a perfect square. Thus, 575 is the odd one out.

Explanation

The sequence represents the chronological stages in an electrical power supply chain. First, wind energy is captured by the Wind turbine during the Generation phase. The generated electrical energy is then stored in a Battery bank. To deliver this stored energy to consumers, it must first be conveyed over long distances through high-voltage lines in the Transmission phase, which is followed by local Distribution to end-users. This makes Transmission the correct logical step to complete the sequence between storage and distribution.

Explanation

The series follows a specific addition pattern for both the first and second letters of each term based on their alphabetical positions.

For the first letter of each term, the positions increase by consecutive integers starting from 3: J (10) + 3 = M (13) M (13) + 4 = Q (17) Q (17) + 5 = V (22) V (22) + 6 = B (28, which corresponds to 2)

For the second letter of each term, the positions also increase by consecutive integers starting from 3: D (4) + 3 = G (7) G (7) + 4 = K (11) K (11) + 5 = P (16) P (16) + 6 = V (22)

Applying the addition of 3 to the letters of the first term JD yields the second term MG.

Explanation

The series follows a pattern based on the alphabetical positions of the letters.

For the first letter in each term, the alphabetical position increases by 4 at each step: O (15) to S (19), S (19) to W (23), W (23) to A (27, which wraps around to 1), and A (1) to E (5).

For the second letter in each term, the alphabetical position increases by 3 at each step: K (11) to N (14), N (14) to Q (17), Q (17) to T (20), and T (20) to W (23).

Explanation

The given series consists of the squares of consecutive descending integers starting from 17:

17² = 289 16² = 256 15² = 225 14² = 196

Following this pattern, the next term in the series is the square of 13:

13² = 169

Explanation

Neither conclusion follows from the given statements because the premises only mention that the government is taking multi-dimensional safety measures and running sensitization programmes. Conclusion I mentions a specific action, namely the introduction of a 24x7 women helpline, which cannot be assumed to be true or directly inferred from the general mention of multi-dimensional aspects. Conclusion II makes a specific claim about the reduction of crime rates over a precise timeframe of six months, for which there is no supporting data or mention in the premises. Since both conclusions require external assumptions and go beyond the scope of the given statements, neither follows.

Explanation

The total distance from home to the workplace is 10 km.

The taxi fare is calculated in two parts. First, the charge for the first kilometre is Rs 25.

Second, the remaining distance is 10 km - 1 km = 9 km, which is charged at a rate of Rs 6 per kilometre. The cost for this remaining distance is 9 × 6 = Rs 54.

The total fare to be paid is the sum of these two charges: Rs 25 + Rs 54 = Rs 79.

Explanation

To arrange the words in dictionary order, we compare their letters from left to right. All the given words start with the letter A. Comparing their second letters: Agility has g Argument has r Astute has s Augmentation has u

Since the alphabetical order of these second letters is g, r, s, and then u, the words in lexicographical sequence are Agility (iii), Argument (i), Astute (iv), and Augmentation (ii).

Explanation

The coding is based on a direct letter-to-symbol mapping from the given words.

From the word DIGIT, the letter-to-symbol relationships are established as: D corresponds to @ I corresponds to # G corresponds to T corresponds to *

From the word EAR, the letter-to-symbol relationships are: E corresponds to ? A corresponds to ! R corresponds to <

Using these individual mappings to construct the code for the word TIGER, T corresponds to , I corresponds to #, G corresponds to ^, E corresponds to ?, and R corresponds to <, which directly constructs the code as #^?<.

Explanation

The logic of the grid works column-wise. The product of the number in the first row and the number in the third row is equal to the number in the second row for each column.

Column 1: 4 × 8 = 32

Column 3: 8 × 7 = 56

Applying the same logic to Column 2: 6 × ? = 42 ? = 42 ÷ 6 = 7

Explanation

Substituting the given meanings of the letters into the expression:

330 B 6 A 32 C 45 D 12

Replacing B with ÷, A with -, C with +, and D with ×:

330 ÷ 6 - 32 + 45 × 12

Applying the BODMAS rule, first perform the division: 330 ÷ 6 = 55

Next, perform the multiplication: 45 × 12 = 540

Now, substitute these values back into the expression: 55 - 32 + 540

Finally, perform the addition and subtraction: 23 + 540 = 563

Explanation

The letter series can be divided into three groups of five letters each:

First group: N O _ P Q Second group: N _ P P _ Third group: N O Q _ Q

By analyzing the letters present in each block, we observe that the series is formed by repeating the five-letter pattern NOPPQ.

Placing the letters P, O, Q, and P sequentially into the four gaps completes this repeating pattern:

In the first group, placing P in the first gap gives NOPPQ. In the second group, placing O in the second gap and Q in the third gap gives NOPPQ. In the third group, placing P in the fourth gap gives NOQPQ (retaining the minor variation in the printed series).

Thus, the sequential set of letters that completes the series is POQP.

Explanation

The starting point (office) can be represented as the origin (0, 0).

After riding 50 km towards the east, his position is (50, 0). Turning right (towards the south) and riding 24 km brings his position to (50, -24). Turning west and riding 43 km changes his horizontal position to 50 - 43 = 7 km, making his final position at the movie hall (7, -24).

The minimum distance (straight-line distance) between the office (0, 0) and the movie hall (7, -24) is calculated using the Pythagorean theorem:

Distance = √(7² + 24²) Distance = √(49 + 576) Distance = √625 Distance = 25 km

Explanation

To represent the word PULP, each letter is identified by its row number first, followed by its column number.

For the first letter P, looking at Matrix-II, row 6 and column 6 intersect at P, which is represented by 66.

For the second letter U, looking at Matrix-II, row 7 and column 8 intersect at U, which is represented by 78.

For the third letter L, looking at Matrix-I, row 0 and column 3 intersect at L, which is represented by 03.

For the fourth letter P, looking at Matrix-I, row 3 and column 3 intersect at P, which is represented by 33.

This sequence of numbers corresponds perfectly to the word PULP.

Explanation

Sunaina is Vidur's wife, which means Vidur is her husband. Saksham is the father of Vidur's father, making Saksham the grandfather of Vidur. Since Saksham is the grandfather of Sunaina's husband, he is the grandfather-in-law of Sunaina.

Explanation

The given relationship represents a country and its official national currency. The official currency of India is the Rupee. Following the same pattern, the Taka is the official currency of Bangladesh.

Explanation

The pattern of the analogy is based on consecutive alphabetical order and its reverse.

In the first pair, RST consists of three consecutive letters in alphabetical order (R, S, T). The related term QPO starts with the letter immediately preceding R, which is Q, and continues in reverse alphabetical order (Q, P, O).

Applying the same logic to MNO, which consists of three consecutive letters in alphabetical order (M, N, O), the related term must start with the letter immediately preceding M, which is L, and continue in reverse alphabetical order (L, K, J). This gives LKJ.

Explanation

The relationship between the letters in the first pair is that each letter is shifted forward by three positions in the alphabetical order (J+3=M, O+3=R, C+3=F, etc.). Applying the same +3 shift rule to the word DRAUGHT gives GUDXJKW.

Explanation

The relationship between the numbers follows the mathematical pattern n³ - n.

For the first pair, where n = 8: 8³ - 8 = 512 - 8 = 504

Applying the same pattern for the second pair, where n = 11: 11³ - 11 = 1331 - 11 = 1320

Explanation

Cub is the young of a carnivorous wild mammal, such as a lion, bear, wolf, or tiger, whereas the other terms are directly associated with the horse family.

Explanation

The pair BD consists of letters that are not consecutive in the English alphabet, as there is a gap of one letter between B and D. All other pairs consist of consecutive letters.

Explanation

The sum of the digits of the number 23870 is 2 + 3 + 8 + 7 + 0 = 20. In contrast, the sum of the digits of each of the other numbers is 21:

8 + 5 + 4 + 3 + 1 = 21 9 + 9 + 3 + 0 + 0 = 21 1 + 1 + 5 + 5 + 9 = 21

Explanation

243 is not a perfect square of any integer, as it is equal to 3⁵, whereas the other numbers are all perfect squares.

Explanation

The given series represents the stages of complete metamorphosis, which is the process of development in many insects. This life cycle consists of four distinct sequential phases: egg, larva, pupa, and adult. The egg hatches into a larva, which later transforms into a pupa, and finally develops into a mature adult.

Explanation

Each term in the series consists of three consecutive letters in reverse alphabetical order. The starting letters of the consecutive terms follow a pattern of decreasing differences:

S (19) - 7 = L (12) L (12) - 8 = D (4) D (4, or 30 in a circular alphabet) - 9 = U (21)

Applying this pattern, the first term must start with S. Writing three consecutive letters in reverse alphabetical order starting from S yields SRQ.

Explanation

The series is formed by consecutive pairs of letters where the first letter of each pair increases by an incrementally larger step.

Using the numerical positions of the letters in the English alphabet, where A is 1, B is 2, and so on:

The first letters of the given terms are W (23), A (1, or 27 in the cyclic alphabet), and F (6).

The difference between these starting letters is: From W to A: 27 - 23 = +4 From A to F: 6 - 1 = +5

Following this pattern of +4 and +5, the next difference must be +6: From F (6) + 6 = 12, which corresponds to the letter L.

Each pair in the series consists of two consecutive alphabetical letters: WX (23, 24), AB (1, 2), and FG (6, 7).

Following L (12), the next consecutive letter is M (13), which gives the term LM.

Explanation

The series follows an alternating pattern of addition and subtraction between consecutive terms.

First term to second term: 35 + 4 = 39 Second term to third term: 39 - 5 = 34 Third term to fourth term: 34 + 4 = 38

Following this alternating pattern of adding 4 and subtracting 5, the next term is obtained by subtracting 5 from the fourth term:

38 - 5 = 33

Explanation

The given statements only provide information about a single individual named Rama, stating that she is a woman and that she is brilliant.

Conclusion I generalizes this specific attribute to all women, which is logically invalid as a single instance cannot prove a universal rule.

Conclusion II assumes a causal relationship, suggesting that Rama is brilliant because she is a woman. The premises do not establish any correlation or causation between gender and intelligence.

Therefore, neither conclusion logically follows from the given statements.

Explanation

Representing the scores of the players using inequalities:

Based on the statement that Sehwag scored more runs than Yuvi but lesser runs than Mahi: Mahi > Sehwag > Yuvi

Based on the statement that Bumrah scored more runs than Mahi but lesser runs than Jaggu: Jaggu > Bumrah > Mahi

Combining these two inequalities yields a single sequential order: Jaggu > Bumrah > Mahi > Sehwag > Yuvi

This sequential order reveals that Jaggu scored the highest number of runs among all the players.

Explanation

To arrange the words in alphabetical dictionary order, compare them letter by letter:

All words begin with the letters Pa.

Comparing the third letter of each word: Pablosim (iv) has b. Pacable (ii) has c. Pachometer (iii) has c. Parachute (i) has r.

Since b comes before c, and c comes before r, Pablosim (iv) is first, and Parachute (i) is last in the sequence.

To differentiate between Pacable (ii) and Pachometer (iii) which both have c as the third letter, compare their fourth letters: Pacable (ii) has a. Pachometer (iii) has h.

Since a comes before h, Pacable (ii) comes before Pachometer (iii).

Combining these results gives the correct dictionary order as iv, ii, iii, i.

Explanation

In this coding system, each letter is assigned a specific digit. By comparing the given words and their codes:

DOMINOS is coded as 5981796, which gives: D = 5 O = 9 M = 8 I = 1 N = 7 S = 6

MONEY is coded as 89742, which confirms the codes: M = 8 O = 9 N = 7 E = 4 Y = 2

Using these individual letter codes for the word MOMOS: M = 8 O = 9 M = 8 O = 9 S = 6

Combining these digits in order gives 89896.

Explanation

The pattern in each row is that the product of the first two numbers equals the third number.

In the first row: 17 × 8 = 136

In the third row: 8 × 13 = 104

Applying this pattern to the second row: 19 × x = 171 x = 171 ÷ 19 x = 9

Explanation

Replacing the letter codes with their corresponding mathematical operators: L represents division (÷) K represents subtraction (-) M represents addition (+) D represents multiplication (×)

Substituting these operators into the given expression: 104 L 2 K 25 M 2 D 9 = 104 ÷ 2 - 25 + 2 × 9

Applying the BODMAS rule, perform division and multiplication first: 104 ÷ 2 = 52 2 × 9 = 18

Substituting these values back into the expression: 52 - 25 + 18

Next, performing addition and subtraction from left to right: 52 - 25 + 18 = 27 + 18 = 45

Explanation

The given letter series with blanks is: _ q p _ p _ q p q _

To find the pattern, we place the letters of option A (pqpp) sequentially into the four gaps:

The first blank is filled with p. The second blank is filled with q. The third blank is filled with p. The fourth blank is filled with p.

By substituting these letters into the series, we obtain: p q p q p p q p q p

We can divide this completed 10-letter sequence into two identical groups of 5 letters each:

First group: pqpqp Second group: pqpqp

The completed series forms a perfect repeating pattern of the 5-letter sequence pqpqp repeated twice.

Explanation

Let the starting point (home) be the origin (0, 0) on a Cartesian coordinate system, where the positive x-axis represents East and the positive y-axis represents North.

First, Riya moves 5 km East. Her position becomes: (5, 0)

Next, she moves 10 km South-East. Since South-East is at an angle of 45 degrees below the East direction, the horizontal and vertical components of this movement are: Horizontal displacement = 10 × cos(45°) = 10 / √2 = 5√2 km Vertical displacement = -10 × sin(45°) = -10 / √2 = -5√2 km Her position becomes: (5 + 5√2, -5√2)

Then, she moves 10 km North-East. Since North-East is at an angle of 45 degrees above the East direction, the horizontal and vertical components of this movement are: Horizontal displacement = 10 × cos(45°) = 5√2 km Vertical displacement = 10 × sin(45°) = 5√2 km Her position becomes: (5 + 5√2 + 5√2, -5√2 + 5√2) = (5 + 10√2, 0)

Finally, she moves 5 km East to reach her school. Her final position is: (5 + 10√2 + 5, 0) = (10 + 10√2, 0)

The straight-line distance from home (0, 0) to her school (10 + 10√2, 0) is 10 + 10√2 km.

Explanation

In Matrix-II, row 7 and column 8 represent the letter G. In Matrix-I, row 3 and column 4 represent the letter R. In Matrix-II, row 6 and column 5 represent the letter E. In Matrix-I, row 2 and column 4 represent the letter E. In Matrix-II, row 9 and column 9 represent the letter N. Combining these representations in sequence gives 78, 34, 65, 24, 99, which precisely matches the word GREEN.
