Answer 1

Answer:

the population of a town increase every year by 10%.if the present population is 180000 what will be the population of the town after 2 year

Answer 2

The population of a town increase every year by 10%.

Present population of town is 180000

⠀⠀⠀⠀⠀⠀⠀

We have to find, population of the town after 2 year.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☯ Let the population of town after 2 years be x.

⠀⠀⠀⠀⠀⠀⠀

Therefore,

Increasement of population every year = 10%

⠀⠀⠀⠀⠀⠀⠀

Present population of town = 180000

⠀⠀⠀⠀⠀⠀⠀

★ 10% of 180000

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{10}{100} \times 180000 = 10 \times 1800 = \bf{18000}$

⠀⠀⠀⠀⠀⠀⠀

☯ Increase in population after 1 year,

⠀⠀⠀⠀⠀⠀⠀

$:\implies$ 180000 + 18000 = 198000

⠀⠀⠀⠀⠀⠀⠀

☯ Increase in population after 2 year,

⠀⠀⠀⠀⠀⠀⠀

$:\implies$ 10% population in 1 year + Population of 1 year

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf \dfrac{10}{100} \times 198000 + 198000$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 19800 + 198000$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\frak{\purple{217800}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore\;{\underline{\sf{The\; Population\;of\;the\;town\;after\;two\;years\;is\; \textbf{217800}}}}.$
