Correct Answer B
Population in state B in 2001 = 250, Population in state B in 2007 = 290 Population rise in state B = 290 - 250 = 40
% rise in population rise in state B = (40/250) × 100 = 16%
Population in state C in 2001 = 99, Population in state C in 2007 = 110, Population rise in state C = 110 - 99 = 11
% rise in population rise in state C = (11/99)× 100 ≈ 11.11%
Population in state D in 2001 = 215, Population in state D in 2007 = 240, Population rise in state D = 240 - 215 = 25
% rise in population in state D = (25/215)× 100 = 11.62 ≈ 12%
Population in state F in 2001 = 175, Population in state F in 2007 = 198, Population rise in state F = 198 - 175 = 23
% rise in population in state F = (23/175) × 100 = 13.14% ≈ 14%
∴ the highest increase in population among the following is state B i.e. 16%
