Answer:
option (B) 20%
Step-by-step explanation:
Data provided in the question:
Earnings before interest and taxes = $20,000
Net income = $10,000
Sales = $50,000
Total assets = $100,000
Now,
Net profit margin = [ Net income ÷ Sales ] × 100%
thus,
Net profit margin = [ $10,000 ÷ $50,000 ] × 100%
or
Net profit margin = 0.2 × 100%
or
Net profit margin = 20%
Hence,
the correct answer is option (B) 20%
