Question

If 20% of x = y, then y% of 20 is same as

• A. 10% of x
• B. 20% of x
• C. 15% of x
• D. 4% of x

Answer 1

The Correct Option is D

To solve this problem, let's start with the given equation:
$$20\% \text{ of } x = y$$
This can be written as:
$$0.2x = y$$
Now, we need to find $y\% \text{ of } 20$. This can be expressed as:
$$\frac{y}{100} \times 20$$
Substitute $y = 0.2x$ into the equation:
$$\frac{0.2x}{100} \times 20$$
Simplify the expression:
$$\frac{0.2x \times 20}{100} = \frac{4x}{100} = 0.04x$$
So, $y\% \text{ of } 20$ is the same as:
Answer: D (4% of x)
