Q. The average of five different positive numbers is 25. x is the decrease in the average when the smallest number among them is replaced by 0. What can be said about x?
Option
a) x is less than 5
b) x is greater than 5
c) x is equal to 5
d) Nothing can be said

• m=(a+b+c+d+e)/5 => 5m=(a+b+c+d+e)
  if e be smallest then after replacing e by 0
  (m-x)=(a+b+c+d+0)/5 => 5(m-x)=a+b+c+d
  subtract 2 from 1
  we get 5x=e => x=e/5
  => if e=25 then x=5 , not possible as sum= 25 & no. are different
  a) x is less than 5

• after getting e=5x in rakesh comment.....
  if e=25 it should not be the least number....hence it should be less than 25
  so x
