Question

175 men can dig a canal 3150m long in 36 days how many men are required to dig a canal 3900m long in 24 days

Answer 1

3150/(175*36)=3900/(x*24)

x=325

Answer 2

Answer:

=3900÷(3150×24)/(36×175)

=(3900×36×175)/(3150×24)

=(78×50×12×3×175)/(63×50×12×2)

=(78×3×175)/(63×2)

=(39×175)/(21)

=(13×175)/7

=13×25

=325

325 men are required
