dontknow1987

On Page 176, Q4, here are my calculation:
In 20101, Net Profit Margin (NPM) would be highest if:
A. Consolidation method = NPM=(69+44*0.5)/(1575+1100*0.5)=4.28%
B. Available for Sale (AFS): NPM=(69+22*0.19)/1575=4.65%
C. Equity method = NPM=(69+44*0.5)/1575=5.97%
Are these correct?
In particular, in consolidation method, if my calculations for NI and Revenue are correct? In AFS, are NI and Revenue correctly computed? Thanks.
