Answer:
i) % in mathematics = 95%
ii) % in hindi = 60%
iii) % in all 5 subjects = 79%
Step-by-step explanation:
i) marks obtained in mathematics = 76
Total marks = 80
% marks = (obtained marks/ total marks) x 100
% marks in maths = (76/80) x 100
% marks in maths = 95%
ii) marks obtained in hindi = 48
Total marks = 80
% marks = (obtained marks/ total marks) x 100
% marks in hindi = (48/80) x 100
% marks in hindi = 60%
iii) total marks obtained in all 5 subjects = 316
Total marks = 400
% marks = (316/400) x 100
% marks = 79%
