Question
P alone can finish a piece of work ‘M’ in 6
days while Q takes 3 days to finish it alone. P, Q and R working together can finish the work ‘N’ which is 6 times of work ‘M’ in 6 days. How long will R take to finish work ‘N’, when working alone?Solution
Let the work ‘M’ = 6 units (LCM of 6 and 3) Efficiency of P = 6/6 = 1 units Efficiency of Q = 6/3 = 2 units Efficiency of P, Q and R = (6 × 6)/6 = 6 units per day Efficiency of R = 6 – (1 + 2) = 3 units per day Time taken by R to finish work ‘N’ = 36/3 = 12 days
Statement: M > N ≥ P > Q ≥ R > S ≥ T ≥ U > W
Conclusion:
1. U ≤ S
2. S < Q
