P, Q and R can complete work for Rs.21000. P, Q and R can alone comple...
Given,
⇒ P’s 1 day’s work = 1/20
⇒ Q’s 1 day’s work = 1/30
⇒ R’s 1 day’s work = 1/60
(P + Q + R)’s 1 days work = 1/20 + 1/30 + 1/60 = (6/60) = 1/10
(P + Q + R + D)’s 1 days work = 1/8
D’s 1 day’s work = 1/8 – 1/10 = 2/80 = 1/40
⇒ P’s 1 day’s work = 1/20
⇒ Q’s 1 day’s work = 1/30
⇒ R’s 1 day’s work = 1/60
(P + Q + R)’s 1 days work = 1/20 + 1/30 + 1/60 = (6/60) = 1/10
(P + Q + R + D)’s 1 days work = 1/8
D’s 1 day’s work = 1/8 – 1/10 = 2/80 = 1/40
Ratio of work efficiency = P : Q : R : D = 1/20 : 1/30 : 1/60 : 1/40 = 6 : 4 : 2 : 3
⇒ P’ share = 21000 × 6/15 = Rs. 8400
⇒ Q’ share = 21000 × 4/15 = Rs. 5600
⇒ R’ share = 21000 × 2/15 = Rs. 2800
⇒ S’ share = 21000 × 3/15 = Rs. 4200
∴ From this, P gets highest share of Rs. 8400.
⇒ P’ share = 21000 × 6/15 = Rs. 8400
⇒ Q’ share = 21000 × 4/15 = Rs. 5600
⇒ R’ share = 21000 × 2/15 = Rs. 2800
⇒ S’ share = 21000 × 3/15 = Rs. 4200
∴ From this, P gets highest share of Rs. 8400.

Given information:
- P, Q, and R can complete work for Rs. 21000.
- P can complete the work alone in 20 days.
- Q can complete the work alone in 30 days.
- R can complete the work alone in 60 days.
- P, Q, R, and D together can complete the work in 8 days.
Calculating efficiency:
- Let's assume that the total work is W.
- P's efficiency = W/20
- Q's efficiency = W/30
- R's efficiency = W/60
- D's efficiency = D/8
Calculating their share:
- The ratio of their efficiencies gives us the ratio of their shares.
- Let's assume P's share = x.
- Therefore, Q's share = (W/20) / x = W / (20x)
- R's share = (W/30) / x = W / (30x)
- D's share = (W/8) / x = W / (8x)
Calculating the total work:
- P, Q, and R together can complete the work in 8 days.
- Therefore, their combined efficiency = W/8
- P's efficiency + Q's efficiency + R's efficiency = W/8
- (W/20) + (W/30) + (W/60) = W/8
Solving the equation:
- Multiplying every term by 120, we get:
- 6W + 4W + 2W = 15W
- 12W = 15W
- 3W = 0
- W = 0
Calculating shares:
- Since the total work is 0, it means that the work cannot be completed.
- However, since the question states that the work is completed for Rs. 21000, it means that there is a mistake in the given information.
- We can assume that the total work is not 0, but it is some positive value.
- In that case, we can calculate the shares of P, Q, R, and D using their respective efficiencies.
Comparing shares:
- Comparing the shares, we find that P gets the highest share of Rs. 8400, which is option 'd'.
So, the correct answer is option 'd', P gets Rs. 8400 as his share.
- P, Q, and R can complete work for Rs. 21000.
- P can complete the work alone in 20 days.
- Q can complete the work alone in 30 days.
- R can complete the work alone in 60 days.
- P, Q, R, and D together can complete the work in 8 days.
Calculating efficiency:
- Let's assume that the total work is W.
- P's efficiency = W/20
- Q's efficiency = W/30
- R's efficiency = W/60
- D's efficiency = D/8
Calculating their share:
- The ratio of their efficiencies gives us the ratio of their shares.
- Let's assume P's share = x.
- Therefore, Q's share = (W/20) / x = W / (20x)
- R's share = (W/30) / x = W / (30x)
- D's share = (W/8) / x = W / (8x)
Calculating the total work:
- P, Q, and R together can complete the work in 8 days.
- Therefore, their combined efficiency = W/8
- P's efficiency + Q's efficiency + R's efficiency = W/8
- (W/20) + (W/30) + (W/60) = W/8
Solving the equation:
- Multiplying every term by 120, we get:
- 6W + 4W + 2W = 15W
- 12W = 15W
- 3W = 0
- W = 0
Calculating shares:
- Since the total work is 0, it means that the work cannot be completed.
- However, since the question states that the work is completed for Rs. 21000, it means that there is a mistake in the given information.
- We can assume that the total work is not 0, but it is some positive value.
- In that case, we can calculate the shares of P, Q, R, and D using their respective efficiencies.
Comparing shares:
- Comparing the shares, we find that P gets the highest share of Rs. 8400, which is option 'd'.
So, the correct answer is option 'd', P gets Rs. 8400 as his share.
