C.
(1M + 3W + 4B)'s 1 h work = 1/96 ...(i)
(2M + 8B)'s 1 h work = 1/80
∴ (1M + 4B)'s 1 h work = 1/160 ...(ii)
Put the value of eq. (ii) in eq. (i),
∴ 3W's 1 h work = 1/96 - 1/160 = 1/240
Now,
(2M + 3W)'s 1 h work = 1/120
∴ 2M's 1 h work = 1/120 - 1/240= 1/240 ...(iii)
As,
(2M + 8B)'s 1 h work = 1/80
∴ 8B's 1 h work = 1/80 - 1/240 = 2/240 = 1/120 (Using (iii))
∴ (5M + 12B)'s 1 h work
∴ (5M + 12B) will finish in
