Question
Raj alone can complete a work in 25 days. Mohan is five
times as efficient as Raj. Find the percentage of work completed by Raj and Mohan together in 5 days.Solution
ATQ,
Let the efficiency of Raj = x units/day
Total work = 25x units
Efficiency of Mohan = x Γ 5 = 5x units/day
Work done by Raj and Mohan together in 5 days = (x + 5x) Γ 5 = 30x units
Percentage of work done = (30x / 25x) Γ 100 = 120%
