Answer 2

Hey! mate ♥️

let 30 men take X days to repair the road.

MORE MEN => LESS DAYS => A CASE OF INDIRECT PROPORTION .

• Inverse ratio of number of men : : Ratio of number of days , I..e., 30 : 12 : : 25 : X

=> 12 × 25 = X × 30 => X = 12 × 25 / 30 => 10

• 30 men take 10 days to repair the road.
