Smallest increase in car occurred in:
1930 - 1940
Explanation:
(The question is incomplete because the chart is not given. I have attached the full question at the bottom, for a better understanding of the question)
Lets calculate the increase from looking at the chart for different options.
In 1900, the number of owners are 0 millions
in 1920, then number of owners are slightly less than 10, consider it to be 8 million.
Increase in ownership = 8 millions - 0 millions
Increase in ownership = 8 millions (approx)
In 1920, the number of owners are 8 millions
in 1930, then number of owners are slightly more than 20, consider it to be 23 million.
Increase in ownership = 23 millions - 8 millions
Increase in ownership = 15 millions (approx)
In 1930, the number of owners are 23 millions
in 1940, then number of owners are slightly less than 30, consider it to be 27 million.
Increase in ownership = 27 millions - 23 millions
Increase in ownership = 4 millions (approx)
In 1940, the number of owners are 27 millions
in 1950, then number of owners are 40 millions
Increase in ownership = 40 millions - 27 millions
Increase in ownership = 13 millions (approx)
