Answer
Explanation:
Step1: Recall ROI formula
ROI = $\frac{Net\ Profit}{Cost\ of\ Investment}\times100%$ Net profit = Sales - Cost of investment. Here, sales = $1200$ and cost of investment = $1000$. So net profit = $1200 - 1000=200$.
Step2: Calculate ROI
ROI = $\frac{200}{1000}\times100% = 20%$

20%
