Question

If in a certain code MONDAY is coded as OPPECZ, then which word is coded as RECORD ?

• A. PCAMPB
• B. PDANPC
• C. QDBNQC
• D. PDAMQC

Hint:

In coding-decoding problems, determine the shift or transformation applied to each letter. Apply the inverse transformation to decode.

Answer 1

The Correct Option is B

Step 1: Identify the coding pattern from MONDAY to OPPECZ.
M (13) $\rightarrow$ O (15) (+2)
O (15) $\rightarrow$ P (16) (+1)
N (14) $\rightarrow$ P (16) (+2)
D (4) $\rightarrow$ E (5) (+1)
A (1) $\rightarrow$ C (3) (+2)
Y (25) $\rightarrow$ Z (26) (+1)
The coding pattern is +2, +1, +2, +1, +2, +1. Step 2: Apply the reverse of this pattern to decode RECORD.
R (18) $\xrightarrow{-2}$ P (16)
E (5) $\xrightarrow{-1}$ D (4)
C (3) $\xrightarrow{-2}$ A (1)
O (15) $\xrightarrow{-1}$ N (14)
R (18) $\xrightarrow{-2}$ P (16)
D (4) $\xrightarrow{-1}$ C (3)
The decoded word for RECORD is PDANPC.
