Quantitative Aptitude • Percentage, Profit & LossHard
In an examination, 26% of the students failed in English, 39% failed in Mathematics and 8% failed in both. What percentage of students passed in both subjects?
A. 8%
B. 27%
C. 43%✓ Correct Answer
D. 35%
💡 Solution & Explanation
Students who failed in at least one subject = failed in English + failed in Mathematics − failed in both (they were counted twice) = 26 + 39 − 8 = 57%. So the students who passed in both = 100 − 57 = 43%. Forgetting to subtract the 8% who failed in both gives 35%, which is too low.
