| 9 | 30 | ? |
(NOTE: Operations should be performed on all numbers without breaking down the numbers into their 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: A
Explanation
The correct answer is option 1 i.e. 7.
Row 1: 5 + (3 × 3) = 5 + 9 = 14
Row 2: 3 + (3 × 7) = 3 + 21 = 24
Row 3: 9 + (3 × 7) = 9 + 21 = 30
