SSC CHSL 2024 PYQs

Question 1

What should come in place of ? in the given series based on the English alphabetical order?PHO SRP VBQ ? BVS

Accepted Answer

The pattern for the first letter is +3, +4, +5, +6. For the second letter, it's +6, +7, +8, +9. For the third letter, it's +2, +3, +4, +5. Applying this, VBQ + (5,8,4) gives YLR.

Question 2

Six numbers 1, 3, 5, 6, 7 and 8 are written on different faces of a dice. Two positions of this dice are shown in the figure. Which is the number on the face opposite to the face containing 6?

Accepted Answer

From the two dice positions, 1 and 5 are common. The remaining numbers on the visible faces are 3 and 6. Therefore, 3 must be opposite to 6.

Question 3

‘Q + R’ means ‘Q is the father of R’‘Q – R’ means ‘Q is the wife of R’‘Q × R’ means ‘Q is the brother of R’‘Q ÷ R’ means ‘Q is the daughter of R’.What does ‘ M – N + O’ mean?

Accepted Answer

M – N means M is the wife of N. N + O means N is the father of O. Therefore, M is the wife of N, who is the father of O, making M the mother of O.

Question 4

What should come in place of the question mark (?) to complete the following letter cluster series?BDC, EGF, HJI, ?

Accepted Answer

The pattern is: first letter moves +3 (B->E->H), second letter moves +3 (D->G->J), and third letter moves +3 (C->F->I). Applying this, H+3=K, J+3=M, I+3=L. So, the next term is KML.

Question 5

Select the correct mirror image of the given figure when the mirror is placed at MN, as shown.

Accepted Answer

When a mirror is placed at MN, the image will be laterally inverted. The left side of the object appears on the right side in the image, and vice versa, while the top and bottom remain unchanged.

Question 6

What should come in place of ? in the given series based on the English alphabetical order?YQI CZQ GIY KRG ?

Accepted Answer

Analyze each letter's position. First letters: Y (+4) C (+4) G (+4) K (+4) O. Second letters: Q (+9) Z (+9) I (+9) R (+9) A. Third letters: I (+18) Q (+18) Y (+18) G (+18) O. Thus, OAO is the correct answer.

Question 7

In a certain code language, ‘mobile switched off” is written as ‘rq mg or’ and ‘turn off light’ is written as ‘my cp rq’. How is ‘off’ written in the given language?

Accepted Answer

Identify the common word 'off' in both phrases. The common code 'rq' appears in both coded sequences. Thus, 'off' corresponds to 'rq'.

Question 8

Six numbers 2, 3, 5, 7, 8 and 9 are written on different faces of a dice, Two positions of this dice are shown in the figure. Which is the number on the face opposite to the face containing 5?

Accepted Answer

From the two dice positions, 7 and 9 are common to both. The remaining numbers on the visible faces are 5 and 3. Therefore, 5 is opposite to 3.

Question 9

How many triangles are there in the given figure?

Accepted Answer

Count triangles systematically: 6 small, 3 medium (2 small), 2 large (3 small), and 3 extra triangles formed by combining parts. Total 6+3+2+3 = 14 triangles.

Question 10

Select the correct mirror image of the given figure when the mirror is placed at AB as shown below.

Accepted Answer

When a mirror is placed at AB, the image will be laterally inverted. The left side of the object becomes the right side in the image, and vice-versa, while the top and bottom remain unchanged.

Question 11

What would be the number on the opposite side of '30' if the given sheet is folded to form a cube?

Accepted Answer

In a standard cube net, alternate faces are opposite to each other. If 30 is on one face, 26 will be its opposite face.

Question 12

Which of the following numbers will replace the question mark (?) in the given series?12, 26, 54, ?, 222, 446

Accepted Answer

The pattern is (previous number * 2) + 2. So, 12*2+2=26, 26*2+2=54. Therefore, 54*2+2=110. Checking the next term: 110*2+2=222.

Question 13

72 is related to 96 following a certain logic. Following the same logic, 66 is related to 88. Which of the following numbers is related to 104 using the same logic?(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

Accepted Answer

The relationship is based on a 3:4 ratio. 72:96 simplifies to 3:4 (72/24=3, 96/24=4). Similarly, 66:88 simplifies to 3:4 (66/22=3, 88/22=4). For 104, find X such that X:104 = 3:4. So, X = (3/4) * 104 = 78.

Question 14

What should come in place of the question mark (?) in the given series?40, ?, 18, 10, 4, 0

Accepted Answer

The series follows a pattern where each number is subtracted by decreasing even numbers: 0-4=-4, 4-10=-6, 10-18=-8. So, 18-? should be -10, making ?=28. Then 28-40 should be -12.

Question 15

What would be the letter on the opposite side of 'R' if the given sheet is folded to form a cube?

Accepted Answer

In a standard cube net, alternate faces are opposite to each other. Here, R is opposite to Q, and S is opposite to T. U and P would be opposite.

Question 16

Which of the following numbers will replace the question mark (?) in the given series?67 100 146 179 225 258 ?

Accepted Answer

The series alternates between adding 33 and adding 46. (67+33=100, 100+46=146, 146+33=179, 179+46=225, 225+33=258). So, the next step is 258 + 46 = 304.

Question 17

If 24 August 1932 was a Wednesday, then what was the day of the week on 11 September 1943?

Accepted Answer

Calculate odd days from 24 Aug 1932 to 11 Sep 1943. 1932 is a leap year. Account for leap years and remaining days in months. Add odd days to Wednesday to find the final day.

Question 18

Which of the following numbers will replace the question mark (?) in the given series?7 28 84 336 1008 ?

Accepted Answer

The pattern alternates between multiplying by 4 and multiplying by 3. So, 7x4=28, 28x3=84, 84x4=336, 336x3=1008. The next step is 1008x4 = 4032.

Question 19

LBXF is related to SYCM in a certain way based on the English alphabetical order. In the same way, TGFY is related to AGHF. To which of the following is ZDMK related, following the same logic?

Accepted Answer

The pattern is +13, -13, +13, -13 for each letter's position. Applying this to ZDMK: Z+13=M, D-13=Q, M+13=Z, K-13=X. So, ZDMK is related to MQZX.

Question 20

What should come in place of? in the given series based on the English alphabetical order?ZRJ EUK JXL ? TDN

Accepted Answer

Analyze each letter's position. Z to E is +5, E to J is +5, so J to O is +5. R to U is +3, U to X is +3, so X to A is +3. J to K is +1, K to L is +1, so L to M is +1. Thus, OAM is the answer.
