total marks is 500
= 500*40%= 200
200+60 = 260 (because Calvin obtained 200 marks and he is failed by 60 marks so he need 60 more marks for getting pass, that's why we added 60 in 200)
260*100/500 = 52%
according to Susie
she got 300 marks
40 marks more than passing so now we less (300-40)= 260
260*100/500 = 52%
hence 52% is passing marks
