In an examination 40% students fail in Mathematics, 30% in English and 15% in both. Find the pass percentage.
- 50%
- 65%
- 30%
- 45%
Answer and explanation
Correct answer: D - 45%
The percentage failing in at least one subject is 40 + 30 - 15 = 55%, since those failing in both are otherwise counted twice. So the percentage passing in both subjects is 100 - 55 = 45%.
