Question

A can complete a piece of work in 3 days . B and A together can finish the same piece of work in 2 days. How many days does B take to complete the work alone?

Answer 1

Answer:

6

Step-by-step explanation:

A can complete a piece of work in 3 days.

So A can complete 1/3 part of work in 1 day.

B and A together can finish the same piece of work in 2 days.

So B and A together can finish 1/2 part of work in 1 day.

So B can complete 1/2-1/3=1/6 part of work in 1 day.

So B can complete work alone in 6 days.
