B
Rs. 4,250

C

In a set of 14 questions, 6 marks are awarded for every correct answer, - 3 marks for every wrong answer and 0 mark for non-attempted questions. Rahul attempted 12 questions. Out of that, he gets 10 correct and 2 wrong answers. What is his score?

A
60

B
54

C
50

D
48

Solution

Number of correct answers given by him = 10
Number of wrong answers given by him = 2
Number of non-attempted questions = 2
Therefore, his score = (6 × 10) + {(- 3) × 2} + (0 × 2) = 54
