The pie chart 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?
Worked solution (try it first)
Maize is marked with a right angle, so it is 90∘.
Beans is the rest: 360∘−60∘−90∘−150∘=60∘.
Millet's 150∘ stands for 3000 tonnes, so 1∘ stands for 3000÷150=20 tonnes.
