Question

A alone can finish a piece of work in 8 days and B alone can do it in 12 days .How many time will be taken,if both A and B work together?​

Answer 1

Answer:

Hi friend,

• Your answer is 4.8 days if A & B work together.

Explanation:

In one day A works 1/8 part of whole work.

Similarly, in one day , B works 1/12 part of the whole work.

So, A & B work (1/8 + 1/12) =5/24 part in one day.

So, A & B work 1 part in 24/5 day =4.8 days
