Question

The population of a town increased from $3025$ in $2008$ to $4300$ in $2010$. Find the absolute and relative(percent) increase.

Answer 1

Finding the absolute and relative increase of population:

Given, population in $2008$ was $3025$

Population in $2010$ was $4300$

Absolute increase in population from $2008$ to $2010$ is,

$$\begin{gathered} =\mathrm{new}\mathrm{value}-\mathrm{old}\mathrm{value} \\ =4300-3250 \\ =1050 \end{gathered}$$

Relative(percent) increase will be,

$$\begin{gathered} =\frac{Absolutevalue}{oldvalue}\times 100 \\ =\frac{1050}{3250}\times 100 \\ =32.3\% \end{gathered}$$

Hence, the absolute and relative increase in population is $1050$and $32.3\%$.
