Explain the details of steps in the answer. u cannot just write final answer in numbers.

you are not doing right(goes to pranjal) by asking 3 questions in one question and that only worth 5 marks.

Ok

Sir ji (goes to Kvnmurty), the 1st answer is incorrect.(According to you)For the correct answers (28 correct answers) he gets 28*2=56 marks and since you have answered that there are 30 questions,he answered 2 wrong and hence -1*2=-2 marks are deducted out of his total,making it 56-2=54, not 56.Infact, Pranjal had to add a detail himself that how many questions were there and then only it is answerable.
