Study the given pattern carefully and select the number that can replace the question mark (?) in it.
| 4 | 6 | 13 |
| 9 | 8 | 21 |
| 5 | 6 | ? |
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. Eg. 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. 14.
The logic used here is:
Row 1:
4 + 6 = 10
10 + (6 ÷ 2) = 10 + 3 = 13
Row 2:
9 + 8 = 17
17 + (8 ÷ 2) = 17 + 4 = 21
Row 3:
5 + 6 = 11
11 + (6 ÷ 2) = 11 + 3 = 14
