SSC CPO 2025 PYQ — Question 176

Given:

DOG → E2F

D → E (+1)

O → 15 → 1 + 5 = 6 → 6 ÷ 3 = 2

G → F (−1)

Thus, pattern is:

First letter +1, middle letter = (sum of digits of position ÷ 3), last letter −1

Now Apply to RUN

R → S (+1)

U → 21 → 2 + 1 = 3 → 3 ÷ 3 = 1

N → M (−1)

So, RUN → S1M

Hence, the correct answer is option 2.
