The sum of two numbers is 289, while the product of two numbers is 120. The total of the numbers is as follows:
A. 20 B. 23 C. 169 D. None of these
Explanation: Let's call the numbers x and yThen xy = 120 and x2 + y2 = 289 are obtained.289 + (2 x 120) = 529 (x + y)2 = x2 + y2 + 2xy = 289 + (2 x 120) = 529,529 = 23. x + y = 529 = 23.
