The product of two numbers is 336 and the sum of their squares is 289. The sum of the number is?  Choose the correct choice: A) A)23 B) B)25 C) C)27 D) D)31 E) E)35
Let the numbers be x and y.   Then, xy = 336 and x2 + y2 = 289.   (x + y)2 = x2 + y2 + 2xy = 289 + (2 x 336) = 961   x + y =31.   Option 31
