Ram can complete a job in 15 days. Shyam alone can complete the same job in 10 days. Ram works for 9 days and then the remaining job is completed by Shyam. How many days will it take shyam to complete the remaining job alone? Correct Answer 4 days

GIVEN:

Ram can complete a job in 15 days

Shyam can complete the same job in 10 days

Ram works for 9 days and then the remaining job is completed by Shyam

CALCULATION:

Ram’s 1 - day work = 1/15

∴ Ram’s 9 days’ work = 9/15 = 3/5

∴ Remaining work = 1 – 3/5 = 2/5 part of the work.

Shyam completes 1 work in 10 days.

∴ Shyam will complete 2/5th part of the work in 10 × 2/5 = 4 days.
