Correct option is B
Given:
9 | 3 | 27 | 36 |
16 | 4 | 64 | 80 |
64 | 8 | 512 | 576 |
A | 7 | 343 | B |
Logic:
Row 1 = (Row 2)2 , Row 3 = (Row 2)3, Row 1 × (Row2 + 1) = Row 5
Now,
9 = 32, 27 = 33, 9 × (3 + 1) = 36
16 = 42, 64 = 43, 16 × (4 + 1) = 80
64 = 82, 512 = 83, 64 × (8 + 1) = 576
Similarly;
A = 72= 49 , 343 = 73,
B = 49 × (7 + 1)
B = 49 × 8
B = 392
Thus, correct option is (B).
