Explanation:
In year 2005 total population living in urban area is equal to sixty eight percent of educated population. The ratio of number of people living in urban area to people living in rural area is 43:12 in 2010. What is the ratio of the rural population in 2005 to that in 2010?.
Total population living in urban area in the year 2005 = 0.68*600 = 408 millions.
Therefore, the population living in rural area in the year 2005 = 900 - 408 = 492 millions.
It is given the the ratio of number of people living in urban area to people living in rural area is 43:12 in 2010.
Hence, the number of people living in rural area in the year 2010 = $$\dfrac{12}{55}\times 1100$$ = 240 millions.
Therefore, the required ratio = 492/240 = 2.05.
