Paper 1 · Mathematical Reasoning and Aptitude
In an examination, 52% of the candidates failed in English, 42% in Mathematics and 17% in both. What percentage passed in both subjects?
A83%
B23% ✓ Correct
C64%
D55.5%
Correct answer: (B) 23% — 23% passed in both subjects, so that is the answer.
Explanation
★23% passed in both subjects, so that is the answer.
★The percentage that failed in at least one subject is 52 plus 42 minus the 17 counted twice.
★That is 52 plus 42 minus 17, which is 77%.
★So 77% failed in at least one subject.
★The rest passed in both, that is 100 minus 77.
★This gives 23%.
