If 20% of x = y, then y% of 20 is same as
Updated On: Jul 16, 2026
- 10% of x
- 20% of x
- 15% of x
- 4% of x
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Write y in terms of x.
Since 20% of x is y, \( y = \frac{20x}{100} = \frac{x}{5} \).
Step 2: Write y% of 20 using that.
\( y\% \) of 20 is \( \frac{y}{100} \times 20 = \frac{y}{5} \).
Step 3: Substitute and simplify.
\( \frac{y}{5} = \frac{1}{5} \times \frac{x}{5} = \frac{x}{25} \), which is \( 4\% \) of x. \[ \boxed{4\% \text{ of } x} \]
Since 20% of x is y, \( y = \frac{20x}{100} = \frac{x}{5} \).
Step 2: Write y% of 20 using that.
\( y\% \) of 20 is \( \frac{y}{100} \times 20 = \frac{y}{5} \).
Step 3: Substitute and simplify.
\( \frac{y}{5} = \frac{1}{5} \times \frac{x}{5} = \frac{x}{25} \), which is \( 4\% \) of x. \[ \boxed{4\% \text{ of } x} \]
