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

400
Let the numbers be x and y and x is greater than y.
As given, xy = 9375 …….. (I)
Again, $latex \frac{x}{y} = 15&s=1$
$latex => x = 15y$
∴ From equation (I),
15y $latex \times$ y = 9375
$latex => y^{2} = \frac{9375}{15} = 625&s=1$
$latex => y = \sqrt{625} = 25$
∴ x = 15y = 15 $latex \times$ 25 = 375
∴ x + y = 375 + 25 = 400
Hence option [C] is right answer.
