Coding and Decoding ( 6 to 10 ):


APTITUDE QUESTIONS (CODING AND DECODING):

6. In a certain code language ‘POLISH’ is written as ‘MLIFPE’. How will ‘DIG’ be written in that code?

A) ZFD

B) AFD

C) BGD

D) EHF

E) None of these

View Answer

ANSWER: OPTION (B)

Explanation:

POLISH => MLIFPE

P – 3= M

O – 3 = L

L – 3 = I

I – 3 = F

S – 3 = P

H – 3 = E

So, in the same way

DIG => AFD

D – 3 = A

I – 3 = F

G – 3 = D

 

7. In a certain code language ‘CAT’ is written as ‘DDY’. How will ‘BIG’ be written in that code?

A) CML

B) CJL

C) CLL

D) CNL

E) None of these

View Answer

ANSWER: OPTION (C)

Explanation:

CAT => DDY

C + 1 = D

A + 3 = D

T + 5 = Y

So, in the same way

BIG => CLL

B + 1 = C

I + 3 = L

G + 5 = L

 

8. In a certain code language ‘POND’ is written as ‘RSTL’. How will ‘HEAR’ be written in that code?

A) GHIZ

B) GHIJ

C) JCLZ


D) JIGZ

E) None of these

View Answer

ANSWER: OPTION (D)

Explanation:

POND => RSTL

P + 2 = R

O + 4 = S

N + 6 = T

D + 8 = L

So, in the same way

HEAR => JIGZ

H + 2 = J

E + 4 = I

A + 6 = G

R + 8 = Z

 

9. In a certain code language ‘ACT’ is written as ‘BGZ’. How will ‘GEL’ be written in that code?

A) HTI

B) HIR

C) HSH

D) HTS

E) None of these

View Answer

ANSWER: OPTION (B)

Explanation:

ACT => BGZ

A + 1 = B

C + 4 = G

T + 6 = Z

So, in the same way

GEL => HIR

G + 1 = H

E + 4 = I

L + 6 = R

 

10. In a certain code language ‘CLOCK’ is written as ‘KCOLC’. How will ‘STEPS’ be written in that code?

A) SPEST

B) SPETS

C) STESP

D) SPTES

E) None of these

View Answer

ANSWER: OPTION (B)

Explanation:

CLOCK => KCOLC

In similar way,

STEPS => SPETS
