Answer:
Decrease from 20% to 16.8%
Step-by-step explanation:
Firstly, we calculate current ROI of the division:
ROI = Margin/Operating asset = 42,000/210,000 = 20%
When the division acquire the new asset, there are following changes in the financials of the company:
- Operating asset will increase to 210,000 + 40,000 = 250,000
- Margin will increase to 42,000 + (10,000 - 10,000) = 42,000.
So, post - purchase ROI will decrease to 42,000/250,000 = 16.8%.
