Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 12 | 51 | 159 |
| 9 | 39 | 123 |
| 8 | 35 | ? |
(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: B
Explanation
The correct answer is option 2 i.e. 111.
The logic used here is:
Row 1: 12 × 4 + 3 = 48 + 3 = 51; 51 × 3 + 6 = 153 + 6 = 159
Row 2: 9 × 4 + 3 = 39; 39 × 3 + 6 = 117 + 6 = 123
Row 3: 8 × 4 + 3 = 32 + 3 = 35; 35 × 3 + 6 = 105 + 6 = 111
