The pie chart given below shows the sales of 7 different companies. The total sales of all these 7 companies are 2880. The sale of a particular company is shown in terms of degree with respect to the total sales of all these 7 companies.
The average sales of G and H is how much percent more than the average sales of D and I?
Answer & explanation
Correct answer: option 4
Total sale of G & H = \(\frac{73º + 13º }{360º}\) × 2880
= \(\frac{86º }{360º}\) × 2880
= 688
Average of G & H = \(\frac{688 }{2}\) = 344
Now ,
Total sale of D & I = \(\frac{17º + 53º }{360º}\) × 2880
= \(\frac{70º }{360º}\) × 2880
= 560
Average of D & I = \(\frac{560 }{2}\) = 280
Required percentage = \(\frac{344 - 280 }{280}\) × 100
= \(\frac{64}{280}\) × 100
= 22.86%
