hi,

according to jee main 2021 marking scheme, for mcq type questions 4 marks would be awarded, for wrong answer 1 marks would be deducted. now coming to numeric value problem there is no negative marking. based on your performance ,

your chemistry correct answer score= 12*4= 48.

negative marking in chemistry= 3*1+2*0(numeric type question.)= 3

your physics score= 9*4= 36

negative marking in physics= 2*1+3*0 = 2

so total score is (48+36)- (3+2)= 79

however you may calculate your overall percentile and rank from below link:
