Question 63

Zee and Gee can complete a task together in 24 days. If the efficiencies of Zee and Gee are in the ratio 3 : 8, respectively, then in how many days can Gee complete the task alone?

Solution

If the efficiencies of Zee and Gee are in the ratio 3 : 8.

Let's assume the efficiencies of Zee and Gee is '3y' and '8y' respectively.

Zee and Gee can complete a task together in 24 days.

Total work = $$24\times(3y+8y)$$

= $$24\times11y$$

= 264y

Time taken by Gee alone to complete the task = $$\frac{264y}{8y}$$

= 33 days
