SSC CHSL 2025 PYQ — Question 26

SSC CHSL - 19 Nov 2025 - Shift 2 • Reasoning • Q26

If in a specific coding system, DOG is coded as 231220, CAT is coded as 24267, and BIRD is coded as 2518923, then following this numerical coding pattern, what would FISH be coded as?

Show answer & explanation

Correct answer: A

Explanation

The coding pattern uses the reverse alphabetical order (opposite letter position).

Reverse position = 27 – Normal Alphabetical position

Verify with the given codes:

DOG:

D (4) – 27-4=23

O (15) – 27-15 = 12

G (7) – 27-7=20

DOG – 231220(Matches)

CAT:

C (3) – 27-3=24

A (1) – 27-1= 26

T (20) – 27-20 = 7

CAT – 24267 (Matches)

Same apply to FISH

F (6) – 27-6=21

I (9) – 27-9 = 18

S (19) – 27-19 = 8

H (8) – 27-8 = 19

So, code for “FISH” is “2118819”.

Hence, the correct answer is option (1).
