Question 125

What are the average marks obtained by all students together in Physics ?

Solution

Average percentage in Physics

= 82 + 84 + 90 + 64 + 70 + 80 = 470 %

= $$\frac{470}{6}$$ %

Max marks in Physics = 150

=> Required average = $$\frac{470}{6}$$ % of 150

= $$\frac{470}{6} \times \frac{150}{100}$$

= $$ \frac{235}{2} = 117\frac{1}{2}$$
