Data Presentation

The pie chart above shows the distribution of the crops harvested from a farmland in a year. If 3000 tonnes of millet is harvested, what amount of beans is harvested?

Diagram for this question
  1. A.9000 tonnes
  2. B.6000 tonnes
  3. C.1500 tonnes
  4. D.1200 tonnes
Show the answer and explanation

Answer: D (1200 tonnes)

Explanation

Maize is a right angle, so beans = 360° − (60° + 90° + 150°) = 60°. Beans = 60/150 × 3000 = 1200 tonnes.
