Question
Ajay alone can complete a work in 50 days. Vijay is four
times as efficient as Ajay. Find the percentage of work completed by Ajay and Vijay together in 10 days.Solution
ATQ,
Let the efficiency of Ajay = x units/day
Total work = 50x units
Efficiency of Vijay = x × 4 = 4x units/day
Work done by Ajay and Vijay together in 10 days = (x + 4x) × 10 = 50x units
Percentage of work done = (50x / 50x) × 100 = 100%
