Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 5 | 39 | 8 |
| 7 | 36 | 5 |
| 11 | ? | 9 |
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /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: A
Explanation
The correct answer is option 1. i.e. 60.
The logic used here is:
Row 1: (5 + 8) × 3 = 13 × 3 = 39
Row 2: (7 + 5) × 3 = 12 × 3 = 36
Row 3: (11 + 9) × 3 = 20 × 3 = 60
