Question

There are 90 multiple choice questions in a test. Suppose you get 2 marks for every

correct answer and for every question you leave unattempted or answer wrongly,

one mark is deducted from your total score of correct answers. If you get 60 marks

in the test, then how many questions did you answer correctly?​

Answer 1

Answer:

Hence, the number of incorrectly answered questions =90−x . It is given that 2 marks are awarded for every correct answer. Hence, we get the number of marks scored for correct answers =2x .

Answer 2

Answer:

Hence, the number of incorrectly answered questions =90−x . It is given that 2 marks are awarded for every correct answer. Hence, we get the number of marks scored for correct answers =2x .
