Correct option is B
Set 1: (7, 175, 5)
7 × (5)² = 175
7×25 = 175
Set 2: (6, 294, 7)
6 × (7)² = 294
6×49=294
Logic: The middle number is obtained by multiplying the first number with the square of the third number.
Option A: (5, 140, 7)
5 × 7² = 5×49 = 245
This does not satisfy the logic.
Option B: (3, 192, 8)
3 × 8²= 3×64=192
This satisfies the logic.
Option C: (6, 216, 5)
6 × 5² = 6×25 = 150
This does not satisfy the logic.
Option D: (8, 412, 9)
8 × 9² = 8×81 = 648
This does not satisfy the logic.
Thus, correct option is (b).
