Question

Answer: C. Both A & B
Solution:
The given number puzzle can be soved in two ways.
Logic 1 ::
Row 1 – 2 x 3 = 6 , 6 x 3 = 18
Row 2 – 4 x 5 = 20 , 20 x 5 = 100
Row 3 – 3 x 7 = 21 , 21 x 7 = 147
Hence, the missing number could be 3.
Logic 2 ::
Row 1 – 6 x (2+1) = 18
Row 2 – 20 x (4+1) = 100
Row 3 – 21 x (6+1) = 147
Hence, the missing number could be 6.
Therefore, 3 or 6 is the right answer.
