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's say that 1 full answer gives 2pts.
So if we have 8 questions - then full answer gives 16pts, but candidate secured only 50% of this points. So candidates earn 8pts.
8 pts gives him 40% total. So:
8pts - 40%
xpts - 100%
40x = 800
x= 20
Answer is 20 questions 
1 5 1
Answer should be 10. The 20 is the total points.Each question carries 2 points.So the number of questions will be 10.
