Please check the info below
Explanation:
1. For Osaka
Margin = Net Operating Income / Sales *100
= $ 792000 / $9900000 *100
= 8.00%
Turnover = Sales / Average Operating Assets * 100
= $ 9900000 / $ 2475000 * 100
= 4.00%
ROI = Margin * Turnover
= 8% *4 %
= 32.00%
Hence the correct answer is 32.00%
For Yokohama :
Margin = Net Operating Income / Sales *100
= $ 2900000 / $ 29000000*100
= 10.00%
Turnover = Sales / Average Operating Assets * 100
= $ 29000000 / $ 14500000* 100
= 2.00%
ROI = Margin * Turnover
= 10% *2 %
= 20.00%
Hence the correct answer is 20.00%
2. The correct answer is
Osaka = $ 371,250
Yokohama = $ 435,000
3. The correct answer is No
This is because since Osaka has a higher ROI, Yokohama’s greater amount of residual income is not an indication that it is better managed

The proportion of the optimal risky portfolio that should be invested in stock A is 0%.
Using this formula
Stock A optimal risky portfolio=[(Wa-RFR )×SDB²]-[(Wb-RFR)×SDA×SDB×CC] ÷ [(Wa-RFR )×SDB²+(Wb-RFR)SDA²]- [(Wa-RFR +Wb-RFR )×SDA×SDB×CC]
Where:
Stock A Expected Return (Wa) =16%
Stock A Standard Deviation (SDA)= 18.0%
Stock B Expected Return (Wb)= 12%
Stock B Standard Deviation(SDB) = 3%
Correlation Coefficient for Stock A and B (CC) = 0.50
Risk Free rate of return(RFR) = 10%
Let plug in the formula
Stock A optimal risky portfolio=[(.16-.10)×.03²]-[(.12-.10)×.18×.03×0.50]÷ [(.16-.10 )×.03²+(.12-.10)×.18²]- [(.16-.10 +.12-.10 )×.18×.03×0.50]
Stock A optimal risky portfolio=(0.000054-0.000054)÷(0.000702-0.000216)
Stock A optimal risky portfolio=0÷0.000486×100%
Stock A optimal risky portfolio=0%
Inconclusion the proportion of the optimal risky portfolio that should be invested in stock A is 0%.

Answer:
50% share.
Explanation:
Given:
There are only three firms in a market.
The largest firm has sales of $500 million.
The second-largest has sales of $300 million.
The smallest has sales of $200 million.
Question asked:
The market share of the largest firm is ?
Solution:
As we know:

Total sales of the largest company = $500 million.
Total sales of the market = Sales of largest firm + Sales of second largest firm+ Sales of smallest firm
Total sales of the market = $500 million + $300 million + $200 million
= $1000 million


Therefore, the market share of the largest firm is 50%.
