the population of a village decreased by 6%.If the total population was 3650.Find the population after decrease.

Answer 1

$$\begin{gathered} \mathrm{Given}\mathrm{that}, \\ \mathrm{The}\mathrm{total}\mathrm{population}=3650 \\ \mathrm{Since}\mathrm{population}\mathrm{of}\mathrm{village}\mathrm{is}\mathrm{decreased}\mathrm{by}6\%,\mathrm{therefore}\mathrm{the}\mathrm{decreased}\mathrm{population} \\ =6\%\mathrm{of}3650 \\ =\frac{6}{100}\times 3650 \\ =219 \\ \mathrm{Now},\mathrm{the}\mathrm{popuation}\mathrm{after}\mathrm{decrease}=\mathrm{Total}\mathrm{population}-\mathrm{Decreased}\mathrm{population} \\ =3650-219 \\ =3431 \\ \mathrm{Hence}\mathrm{the}\mathrm{population}\mathrm{after}\mathrm{decrease}\mathrm{is}3431. \end{gathered}$$
