SSC CGL 2025 PYQs

Question 1

Complete the series. 4, 9, 16, ___, 36

Accepted Answer

The series consists of perfect squares: 2², 3², 4². The next number is 5², which is 25. Then 6² is 36.

Question 2

In the following question, a pair of letters is given, followed by its corresponding product of M x Q : 13 x 17 : : T x F : ?

Accepted Answer

The pattern maps each letter to its alphabetical position. M is 13th, Q is 17th. Similarly, T is 20th and F is 6th. So, T x F becomes 20 x 6.

Question 3

Instruction: In a certain coded language:'study hard learn progress' is coded as 'jkl, hgv, cdf, pqr';'test progress fast study' is coded as 'pqr, mnz, hgv, tuv';'hard work progress success' is coded as 'jkl, efg, pqr, wxy'.Question: What is the code for 'learn hard test work'?

Accepted Answer

By comparing the given statements, we deduce codes for each word: 'learn' is 'cdf', 'hard' is 'jkl', 'test' is 'tuv', and 'work' is 'wxy'. Combining these gives the correct sequence.

Question 4

Eight people are sitting in two parallel rows with 4 people each in such a way that there is equal distance between adjacent persons. In Row I -1, 2, 3 and 4 are seated and all of them are facing south. In Row II - 6, 7, 8 and 9 are seated and all of them are facing north. 1 and 2 are not seated at the extreme ends and 1 sits to the immediate left of 2. 9 and 7 sit opposite 1 and 2 and 7 sits exactly opposite 1. 7 is not the immediate neighbour of 6. Who sits at the extreme right corner of Row II facing north?

Accepted Answer

From the clues, 1 and 2 are in the middle of Row I. 1 is left of 2. 7 is opposite 1, so 7 is in the middle of Row II. 7 is not next to 6. This places 6 at the extreme left. Therefore, 8 is at the extreme right.

Question 5

How many vertices does a cube have?

Accepted Answer

A cube is a 3D shape with 6 faces, 12 edges, and 8 vertices. Visualizing or recalling this basic geometric property directly gives the answer.

Question 6

There are 55 employees in a line. Tina is 18th from the front and Mike is 20th from the back. How many employees are there between them?

Accepted Answer

Tina is 18th from front, Mike is 20th from back. Total employees = 55. Employees between them = Total - (Tina's position + Mike's position) = 55 - (18 + 20) = 55 - 38 = 17.

Question 7

If 5x + y = 16 and x - y = 2, find the value of x.

Accepted Answer

Add the two equations: (5x + y) + (x - y) = 16 + 2. This simplifies to 6x = 18. Dividing by 6 gives x = 3.

Question 8

In each of the following questions, a specific rearrangement pattern is applied to the first word to form the second. Identify the same pattern and apply it to the third word to determine the correct answer from the given alternatives. TARGET : ATGRTE :: WINTER : ?

Accepted Answer

The pattern is to swap letters in pairs: T-A becomes A-T, R-G becomes G-R, E-T becomes T-E. Applying this to WINTER: W-I becomes I-W, N-T becomes T-N, E-R becomes R-E. So, WINTER becomes IWTNRE.

Question 9

A 60 L mixture has milk and water in 4: 1 ratio. How much water should be added to make the ratio 3: 2?

Accepted Answer

Initially, milk is 48L and water is 12L. Let 'x' be water added. New ratio (48) / (12+x) = 3/2. Solving gives 96 = 36 + 3x, so 3x = 60, and x = 20L.

Question 10

In each of the following questions, a specific rearrangement pattern has been applied to the first word to form the second. Apply the same rearrangement to the third word and choose the correct answer from the given alternatives. GEOGRAPHY :EGORGAHPY : : EXPLORERS : ?

Accepted Answer

The pattern is swapping adjacent letters in pairs. G-E becomes E-G, O-G becomes G-O, etc. Applying this to EXPLORERS, EX becomes XE, PL becomes LP, OR becomes RO, ER becomes RE, and S remains S.

Question 11

If 9 @ 4 = 77 and 6 @ 2 = 34, then 7 @ 4 = ?

Accepted Answer

The pattern is $x^2 - y^2$. So, $9^2 - 4^2 = 81 - 16 = 65$. This is not 77. The pattern is $x^2 + y^2$. So, $9^2 + 4^2 = 81 + 16 = 97$. This is not 77. The pattern is $x^2 - y$. So, $9^2 - 4 = 81 - 4 = 77$. This is correct. For $6 @ 2 = 34$, $6^2 - 2 = 36 - 2 = 34$. This is correct. So, for $7 @ 4$, $7^2 - 4 = 49 - 4 = 45$.

Question 12

In each of the following questions, a word is transformed into another using a specific alphabetic pattern (such as letter shifting or substitution). Apply the same transformation to the third word to determine the correct answer from the given options.M E A T : K C Y R : : ? : H F K B D

Accepted Answer

The pattern is -2 for each letter. M(-2)=K, E(-2)=C, A(-2)=Y, T(-2)=R. Applying this in reverse to HFKBD, we get JHMDF.

Question 13

Choose the odd one:

Accepted Answer

Leap years are divisible by 4 (except for century years not divisible by 400). 2004, 2012, and 2024 are all leap years. 2018 is not divisible by 4, making it the odd one out.

Question 14

If 'P' means 'x', 'Q' means '÷', 'R' means '+', and 'S' means '-', what is the value of the following expression? 15 R 5 Q 1 S 2 P 3

Accepted Answer

Substitute the symbols: 15 + 5 ÷ 1 - 2 × 3. Apply BODMAS: 15 + 5 - 6 = 14. The correct answer is 14.

Question 15

X said to Y, "Your grandmother's only son is my father." How is X related to Y?

Accepted Answer

Y's grandmother's only son is Y's father. Since Y's father is also X's father, X and Y are siblings.

Question 16

If the ratio of two numbers is 2:7 and their difference is 45, find the larger number.

Accepted Answer

Let the numbers be 2x and 7x. Their difference is 7x - 2x = 5x. Given 5x = 45, so x = 9. The larger number is 7x = 7 * 9 = 63.

Question 17

In each of the following questions, a group of three numbers/symbols is given in each option. Identify the group that does NOT follow the same pattern (Constant shift of -4) as the others.

Accepted Answer

The pattern is a constant shift of -4 in both letter position and number. Options 1, 2, and 3 follow this. Option 4 shows R(18) to M(13) is -5, and M(13) to I(9) is -4, breaking the consistent -4 pattern.

Question 18

In the following question, the second word is coded from the first using a consistent letter substitution pattern (e.g., positional shift). Identify the logic in the first pair and apply the same to find the correct code for the third word. PLANT : OKZMS : : MONEY : ?

Accepted Answer

The logic is to shift each letter of the word one position backward in the alphabet. P becomes O (-1), L becomes K (-1), A becomes Z (-1), and so on. Applying this to MONEY: M-1=L, O-1=N, N-1=M, E-1=D, Y-1=X. Thus, the code is LNMDX.

Question 19

Find the missing number: 1, 8, 27, 64, ?, 216

Accepted Answer

The series consists of cubes of natural numbers: 1³=1, 2³=8, 3³=27, 4³=64. The next number is 5³, which is 125. The last number is 6³=216.

Question 20

If 6 dollar sign 3 = 45 and 4 dollar sign 5 = 41, then what is 8 dollar sign 2?

Accepted Answer

The pattern is (first number)^2 + (second number)^2. So, 6^2 + 3^2 = 36 + 9 = 45. Similarly, 4^2 + 5^2 = 16 + 25 = 41. Thus, 8^2 + 2^2 = 64 + 4 = 68.
