Answer 1

Answer:  The required value of x is 25.

Step-by-step explanation:  Given that the price of an article of clothing was reduced from$25 to $20. The reduced price of the article is then increased by x% to return it to $25.

We are to find the value of x.

According to the given information, we have

$20+x\%\times 20=25\\\\\\\Rightarrow \dfrac{x}{100}\times20=25-20\\\\\\\Rightarrow \dfrac{x}{5}=5\\\\\\\Rightarrow x=5\times5\\\\\\\Rightarrow x=25.$

Thus, the required value of x is 25.
