Explanation
Rauf's monthly income is Rs. 7200, and the pie graph shows his expenditure on education as 70°. To find the amount spent on education, we calculate the fraction of his income spent on education.
The fraction of income spent on education is 70° out of 360° (total degrees in a circle).
Fraction = 70° / 360° = 7/36
Amount spent on education = (7/36) × 7200 = 7 × 200 = 1400
