    ⇒ 5 C 2 ​ × 5 C 4 ​ ⇒10×5⇒50

    (ii) no. of ways ⇒ selecting 3 questions from each section.

    ⇒ 5 C 3 ​ × 5 C 3 ​ ⇒10×19=100

    (iii) no. of ways ⇒ selecting 4 from section A and 2 from section B

    ⇒ 5 C 4 ​ × 5 C 2 ​ ⇒5×10⇒50

    ∴ Total no. of ways =50+100+50=200.

    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.
