The population of a town was 78787 in the year 1991 and 95833 in the year 2001. Estimate the increase in population by rounding off each population to nearest hundreds.

Population of town in 1991 = 78787

Rounding off to nearest hundred = 78800

Population of town in 2001 = 95833

Rounding off to nearest 100 = 95800

Hence, increase in population by rounding off each population to nearest hundreds = 95800 - 78800 = 17000
