Q.39
Correct Answer is:C
Solution Explain:
(1 + x2)4(1+ x3)7(1 + x4)12 = (4C0 + 4C1x2 + 4C2x4 + 4C3x6 + 4C4 x8)
(7C0 + 7C1x3 + 7C2x6 + 7C3x9 + ……)(12C0 + 12C1x4 + 12C2x8 + ……..)
⇒ coefficient of x11 in (1 + x2)4(1 + x3)7(1 + x4)12
= 4C0 × 7C1 × 12C2 + 4C1 × 7C3 × 12C0 + 4C2 × 7C1 × 12C1 + 4C4 × 7C1 × 12C0
= 1 × 7 × 66 + 4 × 35 × 1 + 6 × 7 × 12 + 1 × 7 × 1
= 462 + 140 + 504 + 7 = 1113
