In a test (+5) marks are given for every correct answer and (−2) marks are given for every incorrect answer. Jay answered all the questions and scored (−12) marks, though he got 4 correct answers. How many of his answers were INCORRECT?
Answer & explanation
Correct answer: option 3
Marks for each correct answer = 5
Attempted correct answer = 4
Marks for each wrong answer = - 2
Total marks scored = -12
Let, the total questions be y
Correct = 4
Incorrect = y - 4
4 x 5 + (- 2)(y - 4) = - 12
2y - 8 = 32
y = 20
Total incorrect answer = y - 4 = 20 - 4 = 16
