If 15% of x is the same as 20% of y, then x:y is:?
- A.
4:3
- B.
3:4
- C.
17:16
- D.
16:17
Correct Answer
A. 4:3Explanation
If 15% of x is the same as 20% of y, it means that the ratio of x to y is equal to the ratio of 15% to 20%. To simplify the ratio, we can divide both sides by 5, resulting in 3% of x being equal to 4% of y. This can be further simplified by dividing both sides by 1%, giving us the ratio of x to y as 3:4. Therefore, the correct answer is 3:4.Rate this question:
