Given :
It is estimated that there are 828 motor vehicles in the US for every 1,000 people.
To Find :
Number of motor vehicles in the US is 260 million, then what is its population to the nearest million.
Solution :
Ratio of car for 1000 people, [tex]R=\dfrac{828}{1000}=0.828[/tex].
Let, population is x million.
[tex]0.828 = \dfrac{260}{x}\\\\x =\dfrac{260}{0.828}\\\\x = 314 \ million[/tex]
Therefore, the population is 314 million.
Hence, this is the required solution.
