Komal and Vimal together can complete a piece of work in 4 days. If Komal alone can complete the same work in 12 days. in how many days can Vimal alone complete that work ?
(Komal+Vimal)'s 1 day's work = 1/4
Komal's 1 day's work = 1/12
Vimal's 1 day's work = (1/4 - 1/12)
Hence, Vimal alone can complete the work in 6 days.
