Q:

The product of two numbers is 9375 and the quotient, when the larger one is divided by the smaller, is 15. The sum of the numbers is :

 A) 100 B) 200 C) 300 D) 400

Explanation:

Let the numbers be x and y.

Then, xy = 9375 and  x/y = 15.

$xyxy=9375/15$

=>

=> y = 25

=> x = 15y = 15 x 25 = 375.

Sum of the numbers = 375 + 25 = 400.
