Question

16 mens are able to complete a piece of work in 12 days working 14 hours a day. How long will 28 men, working 12 hours a day, take to complete the work?

Answer 1

let the days be x

using rule 1

men= 28:16

working hours= 12:14

Days= x

=> 28×12×X=16×14×12

x= 16×14×12 / 28×12

= 8 days
