Question 768122: How can we solve the following problem using Proportion...if 40 men finish a piece of work in 60 days, in how many days will 75 men finish the same work? I was able to solve it using unitary method but not getting correct answer using method of Proportion.Thanks. Answer by josgarithmetic(39613) (Show Source):
You can put this solution on YOUR website! EDIT: Incorrectly stated "days per job" in places where should have said "jobs per day". Now corrected.

Not knowing what is the definition of the "unitary" method, a guess is that this is to determine the rate of work for one man based on the rate of the given reference group of men.
40 men _______________ 60 days, for 1 job
1 man ________________ 60*40 days, for that same 1 job
That one-man rate is JOBS per DAY.
The rate of every man doing a job is additive to find the rate of work of a group of men. If you now want the rate for 75 men, then ... just multiply by the one-man rate:
