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:
Answer: Option
Explanation:
Let the numbers be x and y.
| Then, xy = 9375 and | x | = 15. |
| y |
| xy | = | 9375 |
| (x/y) | 15 |
y2 = 625.
y = 25.
x = 15y = (15 x 25) = 375.
Sum of the numbers = x + y = 375 + 25 = 400.

25*15=375. Once again when you add 25 its 400.

Since units place of product has 5, B and D can be easily ruled out.
Now 9375/15 is 625 which is nothing but 25 sq.
Hence one of the no. is surely 25 and other no. is 25 * 15 = 275.
Hence 380 is also ruled out.
