Study the given pie chart and answer the question that follows.
The total number of students in schools D and E is what percentage more than the total number of students in schools B and C?
 The total degree D and E =$$ 118.8^{\circ} + 61.2^{\circ} = 180^{\circ}$$
so student of D and E = $$\dfrac{180}{360}\times 9000 $$
$$\Rightarrow 4500 $$
again total degree of B and C =$$ 64.8 ^{\circ}+79.2^{\circ}= 144^{\circ}$$
so student of B and C = $$\dfrac {144}{360} \times 9000$$
$$\Rightarrow 3600 $$
% more than total number of students B and C = $$\dfrac{4500-3600}{3600}\times 100 $$
$$\Rightarrow \dfrac{900}{3600}\times 100$$
$$\Rightarrow 25 $$ % AnsÂ
