Answer 1

The way the answer is is same only different no. Mark it as brainliest

If 50 men dug a trench in 60 days,then 70 mens will dug it in less days.

Therefore, it is a case of inverse proportion. ..

let no. of days be Y2

x1=50. y1=60. x2=70. Y2=?

now, x1y1=x2y2

50×60=70× Y2

3000=70×y2

Y2=. 3000÷70

Y2= 42.8 days....

approx 42 days

hope it will help you....
