The pie chart given below shows the number of bikes sold by 8 different companies. The total number of bike sold by all these 8 companies are 2000. The number of bikes sold by a particular company is shown as a percent of the total number of bikes sold by all these 8 companies.
What is the difference between the average number of bikes sold by P, Q, R and S and the average number of bikes sold by T, U, V and W?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 150
Calculation:
The average number of bikes sold by P, Q, R, and S = {(21 +19 + 5 + 20) % × 2000)}/4 = 325
So, the average number of bikes sold by T, U, V, and W = (2000 - 1300)/4 = 175
Now, the difference = 325 - 175 = 150
The difference between the average number of bikes sold by P, Q, R, and S and the average number of bikes sold by T, U, V, and W is 150.
