The mean of the 3 no is 10 more than the least of the no 15 less than the greatest of the 3.if the median of the 3 no is 5,then the sum of the three is?

• (x+y+z)/3=10+x=z-15 where x & z are the least and greatest of the 3 number.
  also, we have y=5.
  solving equation we get x=0,y=5 & z=25. so, x+y+z=30.

• let d numbrs are a,b and c
  so,
  (a+b+c)/3=10+a(taking a as least no.)
  and (a+b+c)/3=c-15
  given, b=5
  solving d abov equations,we get
  a=0;
  b=5;
  c=25
  a+b+c=30

• x+y+z/3=10+x (x least)=z-15(z greatest) and y=5 given
  solving 0,5,25 ..sum=30

• mean of three no is 10.
  (x+y+z)/3=10.
  (0+5+25)/3.
  30/3=10 so ans is 30

• the ans is -5*3=15
