Discussion

Explanation:

Let m and b be 1 day’s work of a man and a boy respectively.

∴ 3m + 4b = 1/8   …(1)

also, 4m + 4b = 1/6   …(2)

Solving (1) and (2)

⇒ m = 1/24 and b = 0

Hence, 1 day’s work of 3 men and 6 boys = 3 × 1/24 + 6 × 0 = 1/8

∴ They will complete the work in 8 days.

Hence, option (a).
