Explanation:

Answer(1)

Population density of village B in 2001 = 400
Then, population density of village E in 2001 = 1600 (since, ratio of population density of a village B to that of village E is 1 : 4)
Population density of village E in 2010 = 800 (50% of 1600)
Population of village E in 2010 = 800 x 4 = 3200
