Study the following graph carefully to answer these questions :
Population of state A in 2005 is what per cent of its total population for all the years together?
Population of state A in 2005 (in millions) = 30
Total population of state A for all the years together (in millions)
= 15 + 25 + 30 + 30 + 40 + 45 = 185
=> Required % = $$\frac{30}{185} \times 100$$
= $$\frac{600}{37} = 16 \frac{8}{37} \%$$
