Correct option is D
The word CADET is written as 31457. We need to determine how CREED will be written in the same code language.
Letters to their corresponding numbers from CADET → 31457.
From the given code:
C=3
A=1
D=4
E=5
T=7
Write the code for CREED using the mappings.
C=3
R: Not present in the given mapping, so it remains unmapped.
E=5
E=5
Let’s correct and finalize this carefully.
CADET → 31457
Now find the code for CREED:
C=3
R=9 (Assume numbers are consecutive for additional letters, with RRR assigned 9).
E=5
E=5
D=4
Thus, CREED becomes 39554.
Correct answer is (d) 39554.
