Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 84.
The logic followed here is (First number - 1) × (Second number - 1) = Third number
1. 13 , 7 , 72 =(13 - 1 ) × ( 7 - 1 ) = 12 × 6 = 72
2. 12 , 6 , 55 = ( 12 - 1 ) × ( 6 - 1 ) = 11 × 5 = 55
3. 8 , 13 , ? = ( 8 - 1 ) × ( 13 - 1 ) = 7 × 12 = 84
Hence, the correct answer is '84' i.e Option 4.
