The following table shows the number of trucks of 6 different brands sold from a showroom during a given period of time.
There are 8 tires on each truck, irrespective of the brand of the truck. What is the average number of tires per brand?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 280
Total number of trucks = 45 + 35 + 36 + 44 + 28 + 22
= 210
There are 8 tires on each truck, irrespective of the brand of the truck.
The total number of tires in all the trucks together = 210 × 8 = 1680
The average number of tires per brand = 1680/6
= 280
