Given:
⇒n-636=852
We have to find the numeric value of the 'n'.
For this on one side of the equation there must be the variable and on the other side the constant should be there.
To isolate 'n' we would add 636 both sides of the equation in case ''i<u>f 636 is positive then we have to subtract 636 on both side of the equation''.</u>
According to the question.

<u>Inverse Proportion</u>
The time needed to complete a job is inversely proportional to the number of men working on it.
It means the more men working, the less time needed to complete the job.
We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:
25 men are needed which means 25-20 = 5 more men should be added.
5 more man should be added
