The sum of two number is 25 and their difference is 13. Find their product.	Choose the correct choice from the following options:
A) 104 B) product=114 C) 315 D) 325 E) None
EXPLANATION   Let the numbers be x and y.   Then, x + y = 25 and x – y = 13.   4xy = (x + y)2 – (x– y)2   = (25)2 – (13)2   = (625 – 169)   = 456   xy = 114.   Answer product=114
