Answer and Explanation:
The computation is shown below:
A.
Return on investment = Margin × Turnover
Now
= (Net operating income ÷Sales) × (Sales ÷ Average operating assets)
Division A = ($414,000 ÷ $6,900,000) × ($6,900,000 ÷ $1,725,000)
= 6% × 4
= 24.00%
Division B = ($1,090,000 ÷ $10,900,000) × ($10,900,000 ÷ $5,450,000)
= 10% × 2
= 20.00%
Division C = ($325,000 ÷ $10,000,000) × ($10,000,000 ÷ $2,500,000)
= 3.25 × 4
= 13.00%
B.
Residual Income = Net operating income - (Minimum required rate of return × Average operating assets)
Division A = $414,000 - (19% × $1,725,000)
= $414,000 - $327,750
= $86,250
Division B = $1,090,000 - (20% × $5,450,000)
= $1,090,000 - $1,090,000
= $0
Division C = $325,000 - (16% × $2,500,000)
= $325,000 - $400,000
= ($75,000)
