Question: 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].380
395
400
425
[A].
[B].
[C].
[D].
Answer: Option C
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.
