Q.

K is 4 times as fast as L and working together, they can complete a work in 24 days. In how many days can L alone complete the work ?

View Answer

Correct choice: A

Explanation:

Given K=4L -->K+L = 4L+L = 5L These 5L people can complete the work in 24 days, which means L alone can do the work in (24 x 5)=120 days. Hence, K alone can do the work in 120/4= 30 days.
