Question

A test has 150 questions. A candidate gets 2
marks for each correct answer and loses 1 mark
for each wrong answer and loses
1/2 mark for
leaving the question unattempted. A student
score 165 marks. If the student left 18 questions
unattempted, find the number of questions he
marked wrong:​

132 - 99 = 33

198 - 33 = 165
