To find :

  We have to find the time taken to do the complete work where 2/7 of the work can be done in 1 hour.

Answer :

  The remaining job can be done in 5/2 hours

Solution :

Let, the complete work = 1

    Work done = 2/7

    Work left to do = 1 - 2/7 = 5/7

2/7 work can be done in 1 hour

1 work can be done in 7/2 hours

5/7 work can be done in (7/2 × 5/7)

                                  = 5/2 hours
