Question

if 20 men can finish a piece of work in 20 days in how many days can 25 men do it​

Answer 1

Answer:

20 multiply 20 divided by 25

Answer 2

Men and days are in direct proportion..

if men power increases, no of days work complete decreases..hence

M1D1=M2D2

(20)(20)=(25)D2

D2=16 days
