Question 60
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 tyres on each truck, irrespective of the brand of the truck. What is the average number of tyres per brand?
Solution
Total number of trucks = 45+35+36+44+28+22
= 210
There are 8 tyres on each truck, irrespective of the brand of the truck.
Total number of tyres in all the trucks together = $$210\times8$$ = 1680
The average number of tyres per brand = $$\frac{1680}{6}$$
= 280
