Direction : Study the following pie chart and answer the questions that follow : Distribution of transport modes in university students Total number of students = 1200
What is the total number of students who commute to the university by both Bus and Car ?
650
Number of students for a sector = (central angle / 360°) × 1200. From the pie chart: Bus = 150°, Car = 45°, Motorcycle = 90°, Bicycle = 75°.
Bus = \(\frac{150}{360} \times 1200 = 500\) and Car = \(\frac{45}{360} \times 1200 = 150\)
Total = 500 + 150 = 650. Check: \(\frac{195}{360} \times 1200 = 650\).
Hence, 650.
