11.27 The price of a certain item was reduced twice - first by $15 \%$, and then by another $20 \%$. What is the overall percentage reduction in price?

## Group B
11.27 Let's take the original price as $100 \%$. Then after the first reduction, the new price will be $100 \%$ $-15 \%=85 \%$ of the original. The second price reduction of $20 \%$ relative to the first will be $85 \% \cdot 0.2=17 \%$ of the original price. Thus, after the second reduction, the new price will be $85 \%-17 \%=68 \%$ of the original. Therefore, the total price reduction is $100 \%-68 \%=32 \%$.

Answer: $32 \%$.
