Question Statement:

An ice cream batch freezer takes in $500\text{ L}$ of liquid ice cream mix and yields $950\text{ L}$ of finished aerated ice cream. The percentage overrun of the product is ________ % (answer in integer).

Answer Key:

90

Step-by-Step Solution & Explanation

Percentage overrun in ice cream manufacture is defined as: $\% \text{ Overrun} = \frac{V_{\text{ice cream}} - V_{\text{mix}}}{V_{\text{mix}}} \times 100$ $\% \text{ Overrun} = \frac{950 - 500}{500} \times 100 = \frac{450}{500} \times 100 = 90\%$
