25 is what percent less than 35
mars1129 [50]
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.
