Question

XYZ Company had an asset turnover last year of 1.6x and its return on total assets was 12%. What was its profit margin?

Answer 1

Asset t/o = Sales/Total Assets = 1.6
so Sales = 1.6A (where A = Total Assets)

Return on total assets = Net income/Total assets = 0.12
so Net income = 0.12A

Net profit margin = Net income/Sales
so replacing the above, we have
Net profit margin = 0.12A/1.6A and the A cancels each other out, so
Net profit margin = 0.12/1.6 = 0.075 or 7.5%
