Exam Tips


Common Mistakes to Avoid


Practice Problems

Problem 1: P/E ratio

Market price = 25. EPS = 1.60.
Find: P/E

Solution: 25 ÷ 1.60 = 15.625 ≈ 16.

Problem 2: EPS

Net profit after preferred = 32,000. Shares = 20,000.
Find: EPS

Solution: 32,000 ÷ 20,000 = 1.60.

Problem 3: Dividend yield

Dividend per share = 0.40. Market price = 25.
Find: dividend yield

Solution: 0.40 ÷ 25 = 0.016 = 1.6%.
