Test-1
Go through the information given below and solve the questions based on it.
Five students – Aman, Gaurav, Chandra, Pooja and Mudit – take an examination in which there are eight questions numbered 1 to 8. Each question has four options – A, B, C and D. Only one of them is right. A student gets one mark for a right answer and loses one third mark for a wrong answer. The answers marked by the five students for each of the eight questions are given below:
| Q1 | Q2 | Q3 | Q4 | Q5 | Q6 | Q7 | Q8 |
Aman | A | B | B | C | D | C | C | A |
Gaurav | A | C | B | D | D | B | D | D |
Chandra | B | B | B | D | D | C | C | D |
Pooja | C | B | B | C | C | B | D | C |
Mudit | A | C | D | B | D | C | C | D |
Following observations are also made:
(1) It is also known that if a student marked the same option (from any of the four options) for all the eight questions, he would have got a total of zero mark.
(2) Gaurav topped the examination with a total of 5.33 marks.
(3) Pooja had the least total score with zero marks.
(4) Had Mudit marked one more answer correctly and Gaurav marked one more answer wrongly, their scores would have interchanged.
(5) Three of the eight questions were answered correctly by Aman as well as Chandra and both of them scored equal marks.
For how many of them is it possible to calculate their exact marks?
