In how many subjects marks obtained are more than the average marks per subject?

Total marks in the examination = 432

Average marks per subject = $$\frac{432}{5}=86.4$$

Marks obtained in :

Hindi = $$\frac{65^\circ}{360^\circ}\times432=78$$

English = $$\frac{75^\circ}{360^\circ}\times432=90$$

Maths = $$\frac{80^\circ}{360^\circ}\times432=96$$

Science = $$\frac{70^\circ}{360^\circ}\times432=84$$

Social Science = $$\frac{70^\circ}{360^\circ}\times432=84$$

Thus, only in 2 subjects (English and Maths), marks obtained are more than the average marks per subject
