Question

The ratio of the working capacity of A and B is 2:3. A takes 10 days more to do a work than B. In how many days A can complete it alone?

Answer 1

Answer:

Answer:

A can complete the work alone is 30 days.

Step-by-step explanation:

It is given that ratio of the capacity to do work of a and b is 3 : 2.

They together can complete the the work in 18 days.

Let the efficiency of a and b are 3x and 2x respectively.

The sum of their efficiency is

Total work is 90x.

The efficiency of a is 3x and the total work is 90x.

Therefore a can complete the work alone is 30 days.
