In a competitive exam with 120 questions, there are three sections: General Knowledge (20 questions), Reasoning (50 questions), and English (50 questions). A candidate answered 70% of General Knowledge, 50% of Reasoning, and 30% of English questions correctly. If the minimum passing score is 60%, how many more questions did the candidate need to answer correctly to pass?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 18.
GK = 70% of 20 = 14
Reasoning = 50% of 50 = 25
English = 30% of 50 = 15
Total correct = 14 + 25 + 15 = 54
Passing marks = 60% of 120 = 72
More needed = 72 − 54 = 18 questions
