Question

The rates of working of A and B are in the ratio 3:4. The number of days taken by them to finish the work are in the ratio

Answer 1

number of days taken by them to finish the work are in the ratio is  inverse of their efficiency

4:3

Answer 2

Answer:

4:3

Step-by-step explanation:

Given :The rates of working of A and B are in the ratio 3:4.

To Find : The number of days taken by them to finish the work are in the ratio

Solution:

The rates of working of A and B are in the ratio 3:4.

Efficiency is inversely proportional to the time

So, the ratio of time of A and B is $\frac{1}{3}:\frac{1}{4}$

So,  the ratio of time of A and B is 4:3

Hence The number of days taken by them to finish the work are in the ratio 4:3
