Ranjith can complete a task in 25 days while Anji can finish it in 20 days. They work together on the task for 5 days and then Ranjith leaves. In how many days will Anji finish the remaining work?
Lcm of 25 and 20 is 100. So total work = 100 unitsÂ
Ranjith can do 4 units per day while anju can do 5 units per day
They together complete 5 days of work i.e 9 x 5 = 45 unitsÂ
The remaining 55 units of work is done by anju in 55/5 days (or) 11 days
Hence, option CÂ is the correct answer.
