A) 33  B) 30  C) 28  D) 27  E) 01
Ans: Median is when the given numbers are arranged in ascending order, the middle one. Let the numbers are x, 5, y where x is the least and y is greatest.   Given that x+5+y3=x+10x+5+y3=x+10   and x+5+y3=y−15x+5+y3=y−15   Solving we get x = 0 and y = 25.   So sum of the numbers = 0 + 5 + 25=
