A candidate attempted 75% of the questions in an exam. He got 80% of the attempted questions correct, and 10% of the unattempted questions were also awarded marks due to grace. If the total number of questions is 200, how many did he get right?
- 130
- 135
- 120
- 125
Correct answer: 125
Solution
He attempted 75% of 200 = 150 questions, and 80% of those were correct, so \(150 \times 0.8 = 120\). Unattempted questions = 50, and 10% of them got grace marks, so \(50 \times 0.1 = 5\). Total right = \(120 + 5 = 125\).
