SSC Selection Post 2025 PYQ — Question 95

39 is coded as 0, 4, 6 →

3 9

Digit 1 → Digit 2

Code digit 1 = (digit 1 ÷ 3) - 1 = (3 ÷ 3) - 1 = 0

Code digit 2 = (digit 1 ÷ 3) + 3 = (3 ÷ 3) + 3 = 4

Code digit 3 = 6 (constant)

Codes = 0, 4, 6

The observed pattern is: Code digit 1 = (first digit ÷ 3) - 1; Code digit 2 = (first digit ÷ 3) + 3; Code digit 3 = 6.

Similarly, let's find the code for 61:

6 1

Digit 1 Digit 2

Code digit 1 = (Digit 1 ÷ 3) - 1 = (6 ÷ 3) - 1 = 1

Code digit 2 = (Digit 1 ÷ 3) + 3 = (6 ÷ 3) + 3 = 5

Code digit 3 = 6 (constant)

Code = 1, 5, 6

Therefore, the code for '61' is 1, 5, 6.

Hence, the correct answer is "Option 2."
