A candidate scoring 50% in an examination fails by 60 marks , while another candidate scores 75% mark, gets 40 marks more than the minimum pass marks . Find the minimum pass mark.
Correct Option is: C Let x be the maximum marks,
Then (50% of x)+60 = (75% of x)-40
x/2 +60 = 3x/4 -20
60+20 = 3x/4 – x/2
X=320
Hence maximum marks = 320
Minimum pass marks = 320/2 + 60 = 220
