The pie chart shows the monthly expenditure of a family on different heads, in degrees. The family earns Rs 2,16,000 every month and the whole income is shown in the chart.
How much (in Rs) does the family spend on children’s education and transport together?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 72000
The whole pie is 360° and stands for the whole income, so a head with \(x^\circ\) gets \(\displaystyle\frac{x}{360}\) of Rs 2,16,000.
Children’s education \(=70^\circ\), transport \(=50^\circ\)
Together \(=70^\circ+50^\circ=120^\circ\)
Amount \(\displaystyle =\frac{120}{360}\times216000=\frac{1}{3}\times216000=72000\)
The family spends Rs 72,000 on the two heads.
