A piece of work can be done by A,B and C working together in 4 days. it can also be finished if A works 2 days; B, 7 days; and C for 5 days. How long will it take each of them to finish the work?

Either you stated the problem wrong or else you're telling the answer
in the problem.

You ask:

How long will it take each of them to finish the work?

Then you tell us:

it can also be finished if A works 2 days; B, 7 days; and C for 5 days.

So the answer to this: 

How long will it take A to finish the work?

is of course 2 days.

The answer to this: 

How long will it take B to finish the work?

is of course 7 days.

And the answer to this: 

How long will it take C to finish the work?

is of course 5 days.

I'm sure you didn't mean to give the answer in the problem.

Please copy it correctly and resubmit it.
