270 men were to finish a piece of work in 14 days .But some men fell sick and the remaining men could complete the work in 21 days. how many men fell sick.?
3-in-1 protection for moms-to-be helps protect baby too.
270 men were supposed to finish a piece of work in 14 days.
1 man would have taken (270 x 14) = 3 780 days
However some fell sick and the rest took 21 days to complete the piece of work
If y men fell sick, (270 - y) men were left.
(270 - y) men took 21 days to finish a piece of work.
3 780 = (270 - y)(21) => 270 - y = 3 780/21 = 180 => y = 90.
90 men fell sick
