Question
Anil can do a piece of work in 14 days and Sunil can do
the same work in 20 days. With the help of Vimal, they completed the same work in just 4 days. Then how much time can Vimal do that work alone?ÂSolution
Anil can do the work in 14 days, so his 1 day work = 1/14 Sunil can do the work in 20 days, so his 1 day work = 1/20 Anil, Sunil, and Vimal together completed the work in 4 days, so their 1 day work together = 1/4 Let Vimal's 1 day work = x So according to the question: 1/14 + 1/ 20 + x = 1/4 x = 9/70 ​So, Vimal’s 1 day work = 9/70 If Vimal does 9/70 of the work in 1 day, then he will complete the full work in: 1(9/70) = 70/9 days
