Question

In a test, a candidate attempted only 10 questions and secured 50% marks in each of the questions. If he obtained a total of 25% in the test and all the questions carried equal marks, how many questions were there in the test?

1. A. 8
2. B. 10
3. C. 15
4. D. 20 (Correct answer)

Correct Answer

Option D — 20

Detailed Solution & Explanation

The correct answer is 20.

Key Points

• The candidate attempted 10 questions, securing 50% marks in each.
• Total marks scored = 10 × (50/100) × m = 5m (where m = marks per question).
• This equals 25% of total marks.
• Let total questions = n. Then 5m = 25% × n×m → 5 = n/4 → n = 20 questions.
