If 175 men can dig a canal which is 3150 m long in 30 days.

let a man digs x m daily.

By equation,

x m * 175 Men * 36 Days = 3150 m

Solving which gives x as 0.5 m

It means each man will dig 0.5 m daily.

By the same equation,

0.5 m * no. of Men * 24 Days = 3900 m

Solving which gives no. of  men as 325 Men

Hence 325 Men are required to dig a canal of 3900 m working for 24 days.
