Please see the following carefully and answer questions. In an examination, 500 candidates appeared for tests in English, Hindi and Mathematics. The diagram presents the number of candidates who failed in different tests:
What is the number of candidates who failed in English subject?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 57
Everyone who failed in English lies somewhere inside the English circle, so all four regions of that circle are added, the overlaps included.
Failed in English only: 30
Failed in English and Hindi only: 10
Failed in English and Mathematics only: 12
Failed in all three subjects: 5
Total who failed in English: \(30+10+12+5=57\)
Tip: The number written alone in the English circle (30, Option (2)) counts only those who failed in English alone.
