In a test, minimum passing percentage for girls and boys are 45% and 60% respectively. A boy scored 767 marks and failed by 313 marks. What are the minimum passing marks for girls?

Explanation:-

Minimum pass percentage for Boys = 60%
A boy gets 767 and failed by 313, it means
767 + 313 = 60%
1080 = 60%
60% = 1080
Or, 1% = 1080/60
Or, 45% = (1080*45)/60 = 810.
So minimum passing marks for girls = 810.
