Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row: 61, 21, 185
Second row: 43, 26, 164
Third row: 39, 16, ?
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its 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. 126.
In first row: (61 × 2) + (21 × 3) = 185
In second row: (43 × 2) + (26 × 3) = 164
Similarly, in third row: (39 × 2) + (16 × 3) = 126
