Explanation:
- The price of sugar has increased by 22%.
- The person wants to limit the increase in expenditure to only 12%.
- To find out the percent decrease in consumption, we use the formula: \[ \text{Required Decrease in Consumption} = \frac{\text{Increase in Price} - \text{Desired Increase in Expenditure}}{1 + \text{Increase in Price}} \]
- Plugging in the numbers: \[ \text{Percent Decrease} = \frac{0.22 - 0.12}{1.22} \]
- Simplifying: \[ \text{Percent Decrease} = \frac{0.10}{1.22} \approx 0.081967 \]
- Converting this into a percentage: \[ \approx 8.2\% \]
- ?? Correct option: 2, 8.2%
