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 percentage of candidates who failed in more than two subjects?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1%
There are only three subjects, so failing in more than two subjects means failing in all three. Only the region common to all three circles counts.
Candidates who failed in all three subjects (the centre of the diagram): 5
Percentage of the 500 candidates: \(\displaystyle\frac{5}{500}\times100=1\%\)
