In a survey of 500 employees, 60% prefer coffee, 25% prefer tea and 15% have no preference. If 20% of coffee drinkers also drink tea, how many employees prefer only tea?
- A. 75
- B. 65
- C. 50
- D. 55
✅ Correct Answer: 65
Explanation
Coffee drinkers $= 500 \times 0.6 = 300$ Tea drinkers $= 500 \times 0.25 = 125$ Both coffee and tea $= 300 \times 0.2 = 60$ Only tea drinkers $= 125 - 60 = 65$
