24 man can complete a piece of work in 15 days. 2 days after the 24 men started working, 4 men left the work. How many more days will the remaining men now take to complete the remaining work?

Answer»

`15 1/3`
`16 4/5`
`11 2/5`
`10 4/5`

Solution :`("WORK")/(man XX DAYS) = ("REMAINING work" )/(men xx days)`
`W/(24xx13) = W/(20 xx D)`
`20 xx D = 24 xx 13`
`D = (24xx13)/20 = 78/5 =15 3/5 ` days
