In a test, a candidate attempted only 8 questions and secured 50% marks in each of the questions. If he obtained a total of 40% in the test and all questions in the test carried equal marks, how many questions were there in the test?
Let x questions be there with 10 marks for each question.
Maximum marks = 10x
8*5 = 40% of 10x
x = 10
The correct option is B.
