**Solutions for Coding and Decoding for SSC CHSL:**

**Solutions:**

**1) Answer (C)**

option A: 49 – 7 ÷ 7 = 14, false

option B: 49 – 7- 7 = 14,false

option C: 49 ÷ 7 + 7 = 14,true

option D: 49 + 7 + 7 = 14,false

the correct answer is option C.

**2) Answer (D)**

If in a certain code, ‘RESPONSES’ is written as ‘ESRONPESS’, then in that code any general group of letters/ numbers 123456789 will be coded as “231564897”. similarly ‘SIGNATURE’ will be coded as ‘IGSATNREU‘.

option D.

**3) Answer (B)**

option A: 8-5 +6 ÷10 =24, not true

option B: 8×5 ×6 ÷10 =24 , true

therefore the correct answer is option B.

**4) Answer (D)**

Any general word abcd that can be coded in the same pattern as dcab. therefore BULB can be coded as BLBU. option D.

**5) Answer (B)**

If 8 * 6 * 96 * 2 =0 then 8×6 -96 ÷2 =48-48=0, can be a solution. which is option B.

**6) Answer (C)**

If each of the letters in the English alphabet is assigned an even numerical value beginning A = 2, B = 4 and so on, then INDIA will total to:

I=18,N=28,D=8,I=18,A=2 .

18+28+18+8+2=74. hence the correct answer is option C.

**7) Answer (A)**

If ‘STYLE’ is written as PQVIB, , then it can be inferred that each letter is represented by the letter that comes before it by 2 places. Similarly SMELL can be coded as PJBII. the correct answer is option A.

**8) Answer (D)**

If BUILDING is coded as 4152 759 6 and RIVER as 85308, then it can be inferred that:

B=4

R=8

I=5

D=7

G=6

E=0. therefore BRIDGE=485760. option D.

**9) Answer (B)**

In this question we need to check options and then decide our answer :

given pattern is 13* 12 *5*4

option A ) = – +

13 = 12 – 5 + 4 , here we can say that 13 =/= 11

option B) = + –

13 = 12 + 5 – 4 , here we can say that 13 =13

hence option B is the correct answer.

**10) Answer (C)**

If In a certain code language Sue Re Nik means She is brave. Pi Sor Re Nik means She is always smiling and Sor Re Zhi means Is always cheerful, then it can be inferred that

Sue Re= she is

is=Re

Sue=she

Sor= always

therefore Pi= smiling and

Zhi= cheerful.

the correct answer is option C.
