The pie chart given below shows the sales of 7 different companies. The total sales of all these 7 companies is 2160. The sale of a particular company is shown in terms of degree with respect to the total sales of all these 7 companies.
The total sales of P, R and S are how much percent less than the total sales of Q, T and U?
Answer & explanation
Correct answer: option 3
Total sale of P , R & S = 26º + 12º + 70º = \(\frac{108º}{360º}\) × 2160
= 648
Total sale of Q , T & U = 150º + 37º + 15º = \(\frac{202º}{360º}\) × 2160
= 1212
Required percentage = \(\frac{1212 - 648}{1212}\) × 100
= \(\frac{564}{1212}\) × 100
= 46.53%
