Question

A and B working together can finish a piece of work in 6 days while a alone can do it in 9 days how much time will be alone take to finish it

Answer 1

Answer:

18 days

Step-by-step explanation:

A and B can together do 1 work in 6 days

So, work done in 1 day by both of them together= 1/6

A can do 1 work in 9 days

So, work done in 1 day by A= 1/9

NOW,

Work done by A in one day +Work done by B in one day

= Work done by A and B together in one day

1/9 +Work done by B in one day = 1/6

Work done by B in one day= 1/9-1/6

                                             =3-2/18

                                              = 1/18

So, B can do 1 work in 18 days.
