Answer 2

Answer:

5:4

Step-by-step explanation:

Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

Given: The ratio of A and B's working rates is 4:5.

To Locate: The days it took them to complete the work are in the ratio

Solution:

The ratio of A and B's working rates is 4:5.

Time and efficiency are inversely related.

Thus, the time ratio between A and B is

Therefore, the time ratio between A and B is 5:4.

Hence The days it took them to complete the work were in the ratio 5:4.
