Question

A takes 20 days more than B to complete a work. If A increases his capacity by 25% and B decreases his capacity by 33.33%, A takes 5 days more than B to complete the work. Find the time taken by A alone to complete the work if he works with his original capacity.​

Answer 1

Step-by-step explanation:

Ratio of times taken by Sakshi and Tanya = 125 : 100 = 5 : 4.

Suppose Tanya takes x days to do the work.

5 : 4 :: 20 : x x = 4 x 20

5

x = 16 days.

Hence, Tanya takes 16 days to complete the work.
