Directions: The percentage distribution of the number of different brands produced in a year by certain factories is shown in the pie chart. The total number of tires sold is 1350.
What is the difference between the average number of Avon and Firestone tires sold together and the average number of Goodyear and Dunlop tires sold together?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 54.
Percentage of Avon and Firestone tires = 21 + 14 = 35%
Number of Avon and Firestone tires = 35/100 × 1350 = 472.5
Average = 472.5/2 = 236.25
Percentage of Goodyear and Dunlop tires = 12 + 15 = 27%
Number of Goodyear and Dunlop tires = 27/100 × 1350 = 364.5
Average = 364.5/2 = 182.25
Thus,
Required difference = 236.25 - 182.25 = 54
