Question
(x) men can do some work in 42 days. If 10 more men
added then the work would have been completed in 30 days, then in how many days (x+45) men can do the same work?Solution
let theĀ Ratio of days is = 42 : 30 = 7 : 5 then Ratio of men will beĀ = 5 : 7 2 units = 10 1 unit = 5 5 units = 5 x 5 = 25 Therefore, (x) = 25 (x + 45) = 70 men Therefore, Number of days taken by (x + 45) men will beĀ = 25 x (42/70) = 15 daysĀ
