Question

A work twice as fast as B work together and complete a job in 10 days. How long would A take to complete yhe job?​

Answer 1

Answer:

The Answer is 15 days

There A completes the task in x days then

B completes the task in 2x days

If they work together..they will finish the task quicker..So B contribution is 1/2

3/2x X 10

15x
