Answer 2

Answer:

20.

Explanation:

Let total number of questions in the exam be x

The candidate attempted 12 of the questions and got full marks in it

It is given that the candidate obtained 60% marks.

Since all the question had equal marks 60% of marks implies 60% of the questions are correct.

The total number of correct question is 12  

Therefore 60% of the total number of question = 12

------->60% of x = 12

------->60x/100 = 12

------->x=12*100/60

therefore x= 20

Total number of questions in the exam = 20.
