Question

If 25 persons can dig a ditch in 36 days
now many persons are required to dig
titch in 9 days?​

Answer 1

As No. Of people increases, working days decreases . So they will be in direct proportion. Let “x” be the no. Of Days when 15 people works,20*12=15*x,

x=(20*12)/15

x=16

So 16 days are required when 15 people are employed to complete the work
