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
= $$\frac{470}{6} \times \frac{150}{100}$$
= $$ \frac{235}{2} = 117\frac{1}{2}$$
