Answer and Explanation:
The computation is shown below:
a The return on assets is
= Net profit before interest after tax ÷ average total assets
= ($2,450,000 + $800,000 × (1 - 0.40)) ÷ ($24,500,000)
= 11.96%
b. The profit margin is
= Net profit before interest after tax ÷ sales
= ($2,450,000 + $800,000 × (1 - 0.40)) ÷ ($49,000,000)
= 5.98%
The asset turnover is
= Sales ÷ average total assets
= $49,000,000 ÷ $24,500,000
= 2 times
c. The return on assets
= Profit margin × total assets
= 2.25 × 5.98%
= 13.455%
