Hello Aspirant,

1/3 negative marking means that for every wrong answer 1/3 mark will be deducted.

In total there are 200 questions asked . And you attempted 116 marks questions, your marks will be 116 as 1 marks are awarded for each correct answer. But you attempted 20 questions wrong, apart from that 116,then you will have 20x1.3=26 deducted. So your total score will be 116-26=90. If you see, then you may notice that 1/3 mark is deducted for every wrong answer and plus 1 mark is deducted as your attempted question gets wrong so it will be counted as unattempted. So total marks deducted for one wrong question is 1+0.3=1.3.

So, your marks is 90.

I hope you can understand.
