Solution

The correct option is A 152
As
$7 \times 1 - 1 = 6$
$6 \times 2 - 2 = 10$
$10 \times 3 - 3 = 27$
$27 \times 4 - 4 = 104$
$104 \times 5 - 5 = 515$
Similarly,
(a) $\Rightarrow 9 \times 1 - 1 = 8$
(b) $\Rightarrow 8 \times 2 - 2 = 14$
(c) $\Rightarrow 14 \times 3 - 3 = 39$
(d) $\Rightarrow 39 \times 4 - 4 = 152$
