In an examination, 25% of the candidates failed in Mathematics and 12% failed in English. If 10% of the candidates failed in both the subjects and 292 candidates passed in both the subjects, which one of the following is the number of total candidates appeared in the examination?
general-mental-abilityquantitative-aptitude
- A300
- B400
- C460
- D500
Explanation
Those failing at least one subject = 25 + 12 − 10 = 27%, so those passing both = 73% = 292 candidates. The total number of candidates is therefore 292/0.73 = 400. Hence (B).
