Question

the population of a town increases by 11% annually. if the present population is 6600000, then what will be the population after 3 years

Answer 1

Hi friend!

$<b><u><big>Answer:</big></u></b>$

Present population = 100% = 66,00,000
Population growth rate = 11% p.a.
After 3 years, population = 100% + (11% of 100%) + (11% of (11% of 100%)) + (11% of (11% of (11% of 100%)))
= 136.76%

136.76% of 66,00,000 = 90,26,364.6 people
People can't be in decimals. So we round off to nearest integer, i. e. 90,26,365.

$Therefore, after 3 years, is population will be <b>90,26,365</b>.$
