If A is a positive integer greater than 1, what is the sum of the multiples of A from A to A^2, inclusive?  Select:
A) A^2(A + 1)/2
B) A(A + 1)(A-1)
C) A^2(A-1)
D) (x^3 + 2x)/2
E) x(x-1)^2
Ans :- A   I substituted 3 in all answer choices.   Option C A were both satisfying the condition.   So i substituted 4 instead of 3 in all answer choices,   A^2(A + 1)/2=A^2(A + 1)/2^2(A^2(A + 1)/2 + 1)/2
<result>A</result>
