SSC CHSL 2017 PYQs

Question 1

Arrange the given words in the sequence in which they occur in the dictionary.i. Obstacleii. Obscureiii. Obsessioniv. Obstruct

Accepted Answer

Compare words letter by letter. 'Obscure' comes first, followed by 'Obsession', then 'Obstacle', and finally 'Obstruct'. This matches option 3.

Question 2

Arrange the given words in the sequence in which they  occur in the dictionary.i. Speakerii. Surreptitiousiii. Spontaneousiv. Spurious

Accepted Answer

Arrange words alphabetically. 'Speaker' comes first, then 'Spontaneous', followed by 'Spurious', and finally 'Surreptitious'. This matches option 4.

Question 3

Arrange the given words in the sequence in which they  occur in the dictionary.i. Ariseii. Abysmaliii. Agilityiv. Accrue

Accepted Answer

Arrange words alphabetically. 'Abysmal' comes first, then 'Accrue', followed by 'Agility', and finally 'Arise'. This matches option 4.

Question 4

Arrange the given words in the sequence in which they occur in the dictionary.i. Victoryii. Victoriousiii. Vaccineiv. Vacancy

Accepted Answer

Arrange words alphabetically. 'Vac' comes before 'Vic'. 'Vacancy' comes before 'Vaccine'. 'Victory' comes before 'Victorious'. So, the order is Vacancy, Vaccine, Victory, Victorious.

Question 5

In a certain code language, "INSTANT" is written as  "IOUWESZ". How is "FORGET" written in that code language?

Accepted Answer

The pattern is +0, +1, +2, +3, +4, +5, +6 for each letter. Applying this to FORGET: F+0=F, O+1=P, R+2=T, G+3=J, E+4=I, T+5=Y. So, FORGET becomes FPTJIY.

Question 6

In a certain code language, "BISLERI" is written as "IREBISL". How is "PANTHER" written in that code language?

Accepted Answer

The word 'BISLERI' is split into two halves: 'BISL' and 'ERI'. The second half 'ERI' is written first, followed by the reverse of the first half 'BISL' which is 'LSIB'. So, 'ERILSIB'. Wait, the example is 'IREBISL'. Let's re-examine. The word 'BISLERI' is reversed to 'IRELSIB'. Then the first three letters 'IRE' are moved to the beginning, and the remaining 'LSB' is reversed to 'BISL'. So, 'IREBISL'. No, this is not correct. The pattern is simpler: the word 'BISLERI' is reversed to 'IRELSIB'. Then, the first three letters 'IRE' are kept as is, and the remaining 'LSIB' is reversed to 'BISL'. So, 'IREBISL'. This is also not correct. Let's try another approach. The word 'BISLERI' is reversed to 'IRELSIB'. The given code is 'IREBISL'. This means the first three letters 'IRE' are kept as is, and the remaining 'LSIB' is reversed to 'BISL'. So, 'IREBISL'. This is the correct pattern. Applying this to 'PANTHER': reverse it to 'REHTNAP'. Keep the first three letters 'REH' as is. Reverse the remaining 'TNAP' to 'PANT'. So, the code is 'REHPANT'.

Question 7

In a certain code language, 'TAPERECORDER' is written as '!#&@^@?%^+@^'. How is 'REPORT' written in thatcode language?

Accepted Answer

Map each letter of 'TAPERECORDER' to its corresponding symbol. Then, substitute the symbols for the letters in 'REPORT' using this mapping to find the coded word.

Question 8

In a certain code language, "TOAST" is written as "56345"  and "TRAIN" is written as "59310". How is "TORN" written in that code language?

Accepted Answer

By comparing 'TOAST' and 'TRAIN', we deduce the code for each letter. T=5, O=6, A=3, S=4, I=1, N=0, R=9. Applying these, TORN becomes 5690.

Question 9

In a certain code language, "REMINDER" is written as "SFNJMCDQ". How is "STANDARD" written in that code language?

Accepted Answer

The pattern is +1, +1, +1, +1, -1, -1, -1, -1 for each letter. Applying this to 'STANDARD' gives S+1=T, T+1=U, A+1=B, N+1=O, D-1=C, A-1=Z, R-1=Q, D-1=C. So, TUBOCZQC.

Question 10

In a certain code language, "CONDITION" is written as  "@#^$*!*#^". How is "NOTION" written in that code language?

Accepted Answer

This is a direct-coding problem. Each letter in 'CONDITION' corresponds to a specific symbol. By mapping the letters of 'NOTION' (N→^, O→#, T→!, I→*), we derive the code ^#!*#^.

Question 11

In a certain code language, "LOYALTY" is written as "MPZBMUZ". How is "PROCLAIM" written in that code language?

Accepted Answer

Each letter in 'LOYALTY' is shifted one position forward in the alphabet to get 'MPZBMUZ'. Applying the same +1 shift to 'PROCLAIM' yields 'QSPDMBJN'.

Question 12

In a certain code language, 'TRUMPET' is written as '7591427' and 'SORROW' is written as '385586'. How is 'EMPRESS' written in that code language?

Accepted Answer

Identify the direct mapping for each letter from the given words. T=7, R=5, U=9, M=1, P=4, E=2, S=3, O=8, W=6. Apply these mappings to 'EMPRESS' to get 2145233.

Question 13

In the following question, select the missing number from the given series.72498351211?1331

Accepted Answer

The series consists of cubes of consecutive prime numbers. 2³=8, 3³=27, 5³=125, 7³=343, 11³=1331. The missing number is 3, as 3³=27.

Question 14

In the following questions select the missing number from the given series.1316996115?260112144441

Accepted Answer

The series consists of numbers and their squares. 13, 169 (13^2); 9, 81 (9^2); 15, ?; 26, 676 (26^2); 12, 144 (12^2); 21, 441 (21^2). Thus, the missing number is 15^2 = 225.

Question 15

In the following question, select the missing number form the given series2562894846569685?

Accepted Answer

The series consists of perfect squares: 16², 17², 22², 25², 31², 34². The pattern for the base numbers is +1, +5, +3, +6, +3. The next base number should be 34+5=39. So, 39² = 1521.

Question 16

If "A" means "plus", "B" means "divide", "C" means  "multiply" and "D" means "minus", then 187 B 17 C 4 A 7 D 17 = ?

Accepted Answer

Substitute symbols with operations: 187 ÷ 17 × 4 + 7 - 17. Following BODMAS, first divide (11), then multiply (44), then add (51), then subtract (34).

Question 17

If "A" denotes "multiplied by", "C" denotes "subtracted from", "D" denotes "added to" and "B" denotes "divided by", then 8 C 45 D 180 B 9 A 11 = ?

Accepted Answer

Substitute symbols with operations: 8 - 45 + 180 ÷ 9 × 11. Apply BODMAS: 8 - 45 + 20 × 11 = 8 - 45 + 220 = 183.

Question 18

If "*" denotes "added to", "&" denotes "divided by", "@" denotes "multiplied by" and "%" denotes "subtracted from", then 153 & 17 @ 6 % 9 * 18 = ?

Accepted Answer

Substitute symbols with operations: 153 ÷ 17 × 6 - 9 + 18. Following BODMAS, calculate 153 ÷ 17 = 9. Then 9 × 6 = 54. Finally, 54 - 9 + 18 = 45 + 18 = 63.

Question 19

If "-" means "plus", "x" means "divided by", "÷" means  "multiply" and "+" means "subtraction", then 25 + 54 x 6 - 20 ÷ 10 = ?

Accepted Answer

First, substitute the new symbols: 25 - 54 ÷ 6 + 20 x 10. Then, apply BODMAS: 25 - 9 + 200. Finally, calculate 16 + 200 = 216.

Question 20

If "A" denotes "added to", "B" denotes "divided by", "C" denotes "multiplied by" and "D" denotes "subtracted from", then 116 B 29 C 6 A 24 D 45 = ?

Accepted Answer

Substitute the symbols: 116 ÷ 29 × 6 + 24 - 45. Following BODMAS, calculate 116 ÷ 29 = 4, then 4 × 6 = 24. Finally, 24 + 24 - 45 = 48 - 45 = 3.
