1.	P alone finish the work in 10 days and Q alone can finish the work in 40 days. They work on alternate days. They took work for Rs.900. Find the share of P.1. Rs.1902. Rs.1803. Rs.2504. Rs.6505. Rs.720
Answer» Correct Answer - Option 5 : Rs.720 Given: P's 1 day's work = 1/10 Q's 1 day's work = 1/40 (P + Q)'s 2 days work = 1/10 + 1/40 = 1/8 (P + Q)'s 4 days work = 2 × 1/8 = 1/4 Similarly, (P + Q)'s 16 days work = 8 × 1/8 = 1 Ratio of their work done = 8/10 : 8/40 = 4/5 : 1/5 = 4 : 1 ∴ Profit share of P = 4/5 × 900 = Rs.720

P alone finish the work in 10 days and Q alone can finish the work in 40 days. They work on alternate days. They took work for Rs.900. Find the share of P.1. Rs.1902. Rs.1803. Rs.2504. Rs.6505. Rs.720

Answer» Correct Answer - Option 5 : Rs.720

Given:

P's 1 day's work = 1/10

Q's 1 day's work = 1/40

(P + Q)'s 2 days work = 1/10 + 1/40 = 1/8

(P + Q)'s 4 days work = 2 × 1/8 = 1/4

Similarly,

(P + Q)'s 16 days work = 8 × 1/8 = 1

Ratio of their work done = 8/10 : 8/40 = 4/5 : 1/5 = 4 : 1

∴ Profit share of P = 4/5 × 900 = Rs.720
