Select the set in which the numbers are related in the same way as are the numbers of the following set.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 9 — 77 — 8.
3 — 20 — 5 → 3 × 5 + 5 = 20
4 — 17 — 3 → 4 × 3 + 5 = 17
Similarly, 9 — 77 — 8 → 9 × 8 + 5 = 77
