Question
The ratio of efficiencies of Ajay and Bijay is 7:8,
respectively. Ajay and Bijay together can complete the total work in 24 days. In how many days will Bijay alone complete the whole work?Solution
ATQ, Let the efficiency of Ajay and Bijay be 7 units per day and 8 units per day, respectively. Total amount of work = (7 + 8) × 24 = 360 units Time taken by Bijay alone to compete the whole work = 360 / 8 = 45 days
