Question

if 5 men can do a work in 10 days and 10 men can do the same work in 5 days .which proportion in this?​

Answer 1

Step-by-step explanation:

Well, on a lighter note:

How many days would 10 men take to do it?

None. Because 5 men already finished the job.

Now, on to the reality. For pure mathematical and theoretical purpose, the answer will be simpler. The job can be done by 5 men in 10 days. If we are to give it to double the number of men, the job will be done twice faster. So 10 men should finish the job in 5 days.

Now, on practical purposes. The answer should be “depending on the job and quality of men”.

If the job is infinite and some one wanted some people to work for 10 days, this renders number of men irrelevant. So 10 men will also take 10 days.

Example: A time keeper, who rings a bell every hour of the day for 10 days.

Answer 2

Answer:

This is indirect proportion
