Difference between 25 and 35 = 35 -25
= 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
= (2/7) * 100
= 200/7
= 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you
have understood the method used to solve this problem. Hopefully you
can do such type of problems without needing any help.
