## Detailed Solution

There are following ways to selecting 5 questions from A and B.

Number of ways of selecting 2 questions from A and 3 from B = 4C2 × 4C3

Number of ways of selecting 3 questions from A and 2 from B  = 4C3 × 4C2

Total number of ways = 4C2 × 4C3 + 4C3 × 4C2

= 2 (4C2 × 4C3) = 2 × 4×32 × 4×3×2 3×2 = 2 × 2 × 3 × 4 = 48.

Hence, 48 is the correct answer.
