Question

If 'KARAMCHAND' is coded as 'ICPCKEFCLF' what should be the code of 'CREATION'?

• A. ATCCRKMP
• B. ETGCVKQP
• C. APCCRJMP
• D. ETCGKRPM

Hint:

In letter-coding, check for alternating operations on consecutive letters (e.g., $-2, +2$). Verifying on a few positions quickly reveals the pattern.

Answer 1

The Correct Option is A

Step 1: Infer the pattern from the example.
KARAMCHAND $\rightarrow$ ICPCKEFCLF
Write letter positions: $K(11)\to I(9)$ ($-2$), $A(1)\to C(3)$ ($+2$), $R(18)\to P(16)$ ($-2$), $A(1)\to C(3)$ ($+2$), $M(13)\to K(11)$ ($-2$), $C(3)\to E(5)$ ($+2$), $H(8)\to F(6)$ ($-2$), $A(1)\to C(3)$ ($+2$), $N(14)\to L(12)$ ($-2$), $D(4)\to F(6)$ ($+2$).
$\Rightarrow$ The rule alternates $-2, +2, -2, +2, \ldots$ on successive letters (alphabetical positions).
Step 2: Apply the rule to "CREATION".
C$(3)\ \xrightarrow{-2}\ $A, \
R$(18)\ \xrightarrow{+2}\ $T, \
E$(5)\ \xrightarrow{-2}\ $C, \
A$(1)\ \xrightarrow{+2}\ $C, \
T$(20)\ \xrightarrow{-2}\ $R, \
I$(9)\ \xrightarrow{+2}\ $K, \
O$(15)\ \xrightarrow{-2}\ $M, \
N$(14)\ \xrightarrow{+2}\ $P.
Therefore, code $=$ $\boxed{\text{ATCCRKMP}}$.
