Question

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.

Answer 1

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
