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 :

[A]380

[B]395

[C]400

[D]425

**400**

Let the numbers be x and y and x is greater than y.

As given, xy = 9375 …….. (I)

Again,

∴ From equation (I),

15y y = 9375

∴ x = 15y = 15 25 = 375

∴ x + y = 375 + 25 = 400

Hence option [C] is right answer.
