Question : Study the pie chart and answer the question.
Distribution (degree wise) of the number of computers sold by a shopkeeper during five months
If the difference between the number of computers sold in March and the number of computers sold in January is x, then x lies between:
Option 1: 200 and 250
Option 2: 300 and 350
Option 3: 250 and 300
Option 4: 150 and 200
Correct Answer: 200 and 250
Solution :
Since the pie chart contains a complete angle of 360$^\circ$
$\therefore$ 360$^\circ$ = 5400
⇒ 1$^\circ$ = 15
The difference between the number of computers sold in March and the number of computers sold in January (x) = (99$^\circ$ – 85$^\circ$) = 14$^\circ$ = 15 × 14 = 210
As we know, 210 lies between 200 and 250.
Hence the correct answer is 200 and 250.
