Question
Quantity I: Akash is 50% more
efficient than Ramesh and three times as efficient as Suresh. Suppose Ramesh and Suresh work together, they can complete the task in 20 days. How many days would it take for Akash to complete the task alone? Quantity II: 20 days In the question, two quantities I and II are given. You have to solve both the quantities to establish the correct relation between Quantity-I and Quantity-II and choose the correct option.Solution
ATQ, Quantity I: Let the time taken by Akash to complete the task be 2a days. Then, time taken by Ramesh alone complete the task = 3a days Time taken by Suresh alone to complete the task = 6a days ATQ, 1/3a + 1/6a = 1/20 3/6a = 1/20, a = 10 So, the time taken by Akash alone to complete the task = 20 days So, Quantity-I = Quantity-II or No relation
