If y exceeds x by 25%, then x is less than y by?A16%B16.33%C20%D16.60%

Let's solve this step by step:

1. We know that y exceeds x by 25%. This means y = x + 25% of x.

2. To find out by how much x is less than y, we need to find the percentage difference between y and x, taking y as the reference point (since the question asks for how much less x is than y).

3. The difference between y and x is y - x. Since y = x + 25% of x, y - x = 25% of x.

4. To express this difference as a percentage of y, we divide it by y and multiply by 100%.

5. Substituting y = x + 25% of x into the equation, we get (25% of x) / (x + 25% of x) * 100%.

6. Simplifying this, we get 20%.

So, x is less than y by 20%. The answer is C) 20%.
