Correct Answer - Option 3 : 750
Given:
A student has to obtain 30% of the total marks to pass. He got 145 marks and failed by 80 marks
Calculation
The student got 145 marks and still, he failed by 80 marks
The minimum pass mark = 145 + 80 = 225
The minimum pass mark = 30% of the total mark
The total mark × 30/100 = 225
The total mark = 22500/30 = 750
Hence, total marks = 750
