There are 3 numbers x,y,z.the mean is m.median is 5.m is 10 more than the smallest number and 15 less than the biggest number.what is x+y+z?

• m=x+y+z/3
  x+y+z=3m
  median is middle number let y=5
  let x is biggest number then x=m+15
  z will be the smallest number then z=m-10
  m+15+5+m-10=3m
  m=10
  then x+y+z=30

• median =y=5
  mean=(x+y+z)/3=m
  given that
  x+10=m
  z-15=m
  hence m=10
  x+y+z=30

• [(m-10)+5+(m+15)]/3=m
  so,m=10
  hence, num wil b 0,5,25.
