In an examination 40% failed in Urdu, 45% failed in English. If 25% students failed in both the subjects. Then the percentage of failed students is________?

Correct answer: C. 60%

  • A. 15%
  • B. 65%
  • C. 60%
  • D. 70%

Explanation

The percentage failing in at least one subject is 40% + 45% - 25% = 60%, subtracting the 25% who failed in both because they were counted twice. Thus, 60% of the students failed in Urdu or English or both. The likely mistake is 85%, which comes from adding the two failure percentages without removing the overlap.
