3% of a family's income is spent on electricity, 59% on food, 20% on transport, 11% on education and 7% on extended family. The angles subtended at the centre of the pie chart under education and food are respectively
76.8o and 25.2o
10.8o and 224.6o
112.4o and 72.0o
39.6o and 212.4o
Correct answer is D
Education = 11% = \(\frac{11}{100} \times 360° = 39.6°\)
Food = 59% = \(\frac{59}{100} \times 360° = 212.4°\)
