Question

In the question, two Quantities I and II are given. You have to solve both the Quantity to establish the correct relation between Quantity-I and Quantity-II and choose the correct option. Vikram is four times as efficient as Akash whose efficiency is one-third of the efficiency of Pankaj. If all of them work together, then the work gets complete in 35 days. Quantity-I: What is the time taken by Vikram and Pankaj to complete the work if both of them work on alternate days starting with Vikram? Quantity-II: What is the time taken by Vikram and Akash to complete the work together?

Q: Answer-In the question, two Quantities I and II are given. You have to solve both the Quantity to establish...

Let the efficiency of Pankaj be 3e unitsday. Efficiency of Akash 13 X 3e e unitday Efficiency of Vikram 4 X 1e 4e unitsday Total work 4e e 3e X 35 280e units Quantity I Work done by Vikram and Pankaj in first 2 days 4e 3e 7e units Time taken by them to complete the work 280e7e X 2 80 days So, Quantity I 80 days Quantity II Time taken by Vikram and Akash to complete the work 280e 4e e 56 days So, Quantity II 56 days Therefore, Quantity-I Quantity-II Hence, option a.
