Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 54 | 72 | 90 |
| 79 | 97 | 115 |
| 83 | 101 | ? |
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 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: C
Explanation
The correct answer is option 3 i.e. 119.
The logic used here is:
Row 1: 54 + 18 = 72; 72 + 18 = 90
Row 2: 79 + 18 = 97; 97 + 18 = 115
Row 3: 83 + 18 = 101; 101 + 18 = 119
