If 12 persons working 16 h per day earn ₹ 33600 per week, then how much will 18 persons earn working 12 h per day ?

1. ₹ 40000
2. ₹ 35000
3. ₹ 28800
4. ₹ 37800

Correct Option: D

M₁ = 12 H₁ = 16, W₁ = 33600
M₂ = 18, H₂ = 12, W₂ = ?
By formula, M₁H₁/W₁ = M₂H₂/W₂
(12 x 16)/33600 = (18 x 12)/W₂
⇒ W₂ = (33600 x 18)/16
⇒ W₂ = 2100 x 8
∴ W₂ = 37800
