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
