SSC CHSL 2024 PYQs

Question 1

What should come in place of the question mark (?) in the given series?3977, 3877, 3777, 3677, 3577, ?

Accepted Answer

The series follows a simple arithmetic progression where each subsequent number is 100 less than the previous one. Subtract 100 from 3577 to get 3477.

Question 2

HJKN is related to EGHK in a certain way based on the English alphabetical order. In the same way, QSTW is related to NPQT. To which of the following is IKLO related, following the same logic?

Accepted Answer

The pattern is a -3, -3, -3, -3 shift for each letter. H-3=E, J-3=G, K-3=H, N-3=K. Applying this to IKLO: I-3=F, K-3=H, L-3=I, O-3=L. So, IKLO is related to FHIL.

Question 3

Select the set in which the numbers are related in the same way as are the numbers of the following sets.(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/deleting/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.)(10, 5, 20)(14, 7, 28)

Accepted Answer

The pattern is: the second number is half of the first, and the third number is double the first. (10/2=5, 10*2=20). Option 3 follows this: (22/2=11, 22*2=44).

Question 4

How many squares are there in the given figure?

Accepted Answer

Count squares of different sizes. There are 9 small squares, and 2 larger squares (one 2x2 and one 3x3). Total 9 + 2 = 11 squares.

Question 5

In a certain code language,A + B means ‘A is the son of B’A – B means ‘A is the brother of B’A × B means ‘A is the wife of B’A ÷ B means ‘A is the father of B’Based on the above, how is P related to T if ‘P × Q − R + S ÷ T ’?

Accepted Answer

Decode the expression: P is Q's wife, Q is R's brother, R is S's son, S is T's father. This means Q is T's son, and P is Q's wife. So, P is T's son's wife, i.e., daughter-in-law.

Question 6

If 9 March 2007 was Friday, then what was the day of the week on 13 March 2012?

Accepted Answer

From March 9, 2007 to March 9, 2012, there are 5 years, including 2 leap years (2008, 2012). Total odd days = 5 + 2 = 7. So, March 9, 2012 was Friday. Adding 4 days (13-9) makes it Tuesday.

Question 7

HF 16 is related to KI 8 in a certain way. In the same way, RP 10 is related to US 5. To which of the following is NL 6 related, following the same logic?

Accepted Answer

The pattern is: first letter +3, second letter +3, and number divided by 2. Applying this to NL 6: N+3=Q, L+3=O, 6/2=3. So, the answer is QO 3.

Question 8

If 'H' stands for '÷', 'A' stands for '+', 'B' stands for '-' and 'L' stands for '×' what will come in place of the question mark (?) in the following equation?84 H 42 A 63 L 46 B 23 = ?

Accepted Answer

Substitute the symbols with their respective operations: 84 ÷ 42 + 63 × 46 - 23. Follow BODMAS: 2 + 2898 - 23 = 2900 - 23 = 2877.

Question 9

In a certain code language. 'messages are encrypted' is written as 'tg gc mz' and 'are you coming' is written as 'ze fp mz'. How is 'are' written in the given language?

Accepted Answer

Compare the two given statements. The common word is 'are'. The common code in 'tg gc mz' and 'ze fp mz' is 'mz'. Thus, 'are' is coded as 'mz'.

Question 10

The position of how many letters will remain unchanged if each of the letters in the word ‘ABDUCTS’ is arranged in English alphabetical order?

Accepted Answer

Original word: ABDUCTS. Alphabetical order: ABCDSTU. Comparing positions, 'A', 'B', and 'S' remain unchanged. Thus, three letters.

Question 11

What will come in the place of '?' in the following equation, if '+' and '÷' are interchanged and '×' and '-' are interchanged?21 + 3 - 7 ÷ 11 × 4 = ?

Accepted Answer

Interchange the operators as given: '+' becomes '÷', '÷' becomes '+', '-' becomes '×', '×' becomes '-'. The equation becomes 21 ÷ 3 × 7 + 11 - 4. Following BODMAS: 7 × 7 + 11 - 4 = 49 + 11 - 4 = 60 - 4 = 56.

Question 12

How many triangles are there in the following figure?

Accepted Answer

Count triangles systematically: 6 small, 3 medium (formed by 2 small), and 1 large overall triangle. Total 6 + 3 + 1 = 10 triangles.

Question 13

Which letter-cluster will replace the question mark (?) to complete the given series?NDGB, OFJF, ?, TMSQ, XRYX

Accepted Answer

Analyze each letter's position in the series. The first letter follows N+1, O+2, Q+3, T+4, X. The second letter follows D+2, F+3, I+4, M+5, R. The third letter follows G+3, J+4, N+5, S+6, Y. The fourth letter follows B+4, F+5, K+6, Q+7, X. Thus, the missing cluster is QINK.

Question 14

In a certain code language,‘A @ B’ means ‘A is the husband of B’,‘A # B’ means ‘A is the mother of B’,‘A & B’ means ‘A is the sister of B’.Based on the above, how is T related to P if ‘P @ Q # R & S @ T’?

Accepted Answer

P @ Q means P is husband of Q. Q # R means Q is mother of R. R & S means R is sister of S. S @ T means S is husband of T. So, R is S's sister, S is T's husband. Thus, T is S's wife. R is Q's child, and S is also Q's child. P is Q's husband. Therefore, S is P's son, and T is P's son's wife.

Question 15

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.Statements:Some keys are chains.All chains are locks.No lock is a rock.Conclusions:(I) No rock is a key.(II) At least some keys are locks.

Accepted Answer

From 'Some keys are chains' and 'All chains are locks', it follows that 'Some keys are locks'. So, conclusion II is true. 'No lock is a rock' means no chain is a rock, but some keys can still be rocks.

Question 16

In this question, three statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusion(s) logically follows/follow from the statements.Statements:All rings are earrings.Some rings are chains.All chains are bangles.Conclusions:I. Some rings are bangles.II. Some earrings are bangles.III. Some chains are earrings.

Accepted Answer

Draw Venn diagrams for the statements. 'Some rings are chains' and 'All chains are bangles' implies 'Some rings are bangles' (I). 'All rings are earrings' and 'Some rings are bangles' implies 'Some earrings are bangles' (II). 'All rings are earrings' and 'Some rings are chains' implies 'Some chains are earrings' (III). All conclusions follow.

Question 17

Which of the following numbers will replace the question mark (?) in the given series?119 171 223 275 327 ?

Accepted Answer

The series follows an arithmetic progression where each subsequent number is obtained by adding 52 to the previous one. So, 327 + 52 = 379.

Question 18

If the seventh day of a month is three days earlier than Friday, then what day will it be on the 20thday of the month?

Accepted Answer

If the 7th day is 3 days before Friday, it's Tuesday. From Tuesday (7th), count 13 days forward to reach the 20th. Since 13 = 1 week + 6 days, the 20th will be 6 days after Tuesday, which is Monday.

Question 19

What should come in place of the question mark (?) in the given series?27, 32, 42, 47, 57, ?

Accepted Answer

The pattern is +5, +10, +5, +10, +5. Following this, the next number is 57 + 5 = 62.

Question 20

In a certain code language. ‘MENIAL’ is coded as ‘NIEAML’ and ‘INCOME' is coded as ‘CONMIE’. What is the code for ‘FOREGO’ in the given code language?

Accepted Answer

The letters of the word are rearranged. If the original positions are 123456, the new arrangement is 342516. Applying this pattern to 'FOREGO' (F-1, O-2, R-3, E-4, G-5, O-6) gives 'REOGFO'.
