Question
Amit and Bheem can individually
finish a task in 10 days and 15 days, respectively. If they work together to complete the task and earn a total payment of Rs. 600, how much of the payment does Amit receive?Solution
ATQ, Let total task = 30 units {LCM of 10 and 15} Efficiency of 'Amit' = 3 units per day Efficiency of 'Bheem' = 2 units per day Since, they completed the whole task together therefore ratio of wage received by them will be same as the ratio of their efficiencies. So, required wage received by 'Amit' = {3/(3 + 2)} × 600 = Rs. 360
