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?
Answer & explanation
Correct answer: option 4
Total number of students in school D & E = ( 61.2º + 118.8º ) = 180º
Total number of students in school B & C = ( 64.8º + 79.2º ) = 144º
Required percentage = \(\frac{180 - 144 }{144}\) × 100
= \(\frac{36}{144}\) × 100
= 25%
