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

Answer: Increase in population in 10 years is 17000, and increase in population in each year is 1700.

Step-by-step explanation:

Since we have given that

Population of a town in the year 1991 = 78787

Population of a town in the year 2001 = 95833

We need to find the increase in population :

Population in 1991 nearest to hundreds = 78800

Population in 2001 nearest to hundreds = 95800

Change in population is given by

$95800-78800\\\\=17000$

Change in population in each year is given by

$\frac{95800-78800}{2001-1991}\\\\=\frac{17000}{10}\\\\=1700$

Hence, increase in population in 10 years is 17000, and increase in population in each year is 1700.

Answer 2

Answer:

The population of a town in 1991 = 78787

and the population of that town in 2001 = 95833

78787 is rounded off the nearest hundreds

= 78800

95833 is rounded off to nearest hundreds

= 95800

∴

The estimated increase in population

= 95800 – 78800 = 17000
