A person want to score 120 marks put of 135. What should be his accuracy race so that he can score his desired marks?

Hi Shubham,
I am slightly confused if that's a quant question or some exam related query. I will answer both.
If it's a quant question then the answer should be cannot be determined as nothing is given regarding the pattern of negative marking. If it is related to some exam,
then if negative marking is 1/4 the required accuracy has to be around 92%.
Hope that clears the things.
All the best
