SSC Selection Post 2025 PYQ — Question 99

BLOCK → BCFCB

Look at the position of the letters:

B L O C K

Code:

B C F C B

Now, the letters are numbered:

• B = 2 → B

• L = 12 → 12 = 1 + 2 = 3 → C

• O = 15 → 1 + 5 = 6 → F

• C = 3 → C

• K = 11 → 1 + 1 = 2 → B

That is, each letter is converted to a letter according to the sum of the digits of its alphabetical number.

Now for MOBILE:

• M = 13 → 1 + 3 = 4 → D

• O = 15 → 1 + 5 = 6 → F

• B = 2 → B

• I = 9 → I

• L = 12 → 1 + 2 = 3 → C

• E = 5 → E

So the code is:

DFBICE

Correct answer: (3) dfbice.
