Answer 1

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,
`R=(828)/(1000)=0.828`.

Let, population is x million.

`0.828 = (260)/(x)\\\\x =(260)/(0.828)\\\\x = 314 \ million`

Therefore, the population is 314 million.

Hence, this is the required solution.
