In the year 2005, total production living in urban area is equal to sixty eight percent of educated population. The ratio of number of people living in urban areas to people living in rural areas is 43:12 in 2010. What is the ratio of the rural population in 2005 to that in 2010?

• A. 0.8
• B. 0.47
• C. 2.05
• D. None

Answer 1

The correct option is C

2.05

Population living in urban area in 2005 = 0.68 × 600 = 408 million.
Population living in rural area in 2005 = 492 million.
Rural population in 2010 = $\frac{12}{55}$ $\times$ 1100 = 240 million

Hence, required ratio = $\frac{492}{240}$ = 2.05
