If 5 ppls takes 10 days to build a wall then 15 ppls take how many days to build the same wall
Ans:
No. of people is inversely proportional to the time taken to build the same. i.e. More people means less time and vice versa.
5 people take 10 days.
So the wall requires 5*10 = 50 person-days of work to build.
So, if 15 people were there, the time taken would be
50/15 = 3.33 days

Hope you got it:)
