Jagdish can build a wall in 10 days. Narender can build the same wall in 12 days while submitting takes 15 days to do the same job. Which two of them should be employed to finish the job in 6 days?
- The work done by Jagdish in one day = 1/10
- The work done by Narender in one day = 1/12
- The work done by Sumit in one day = 1/15
Hence, work done by both Jagdish and Sumit in one day is
= 1/10 + 1/15
= (3 + 2)/30
Hence, the total number of days required for Jagdish and Sumit to complete the work = 6 days.
So Jagdish and Sumit should be employed to finish the job in 6 days.
