The population of a town grows by $10\%$ every year. If the present population is $1{,}33{,}100$, what was it $3$ years ago? / एक कस्बे की जनसंख्या हर वर्ष $10\%$ बढ़ती है। यदि वर्तमान जनसंख्या $1{,}33{,}100$ है, तो $3$ वर्ष पहले कितनी थी?

$1{,}10{,}000$
3.
$1{,}21{,}000$
4.
$99{,}000$

Correct Answer: $1{,}00{,}000$

$P(1.10)^3 = 133100$, so $P = \frac{133100}{1.331} = 100000$. / $P(1.10)^3 = 133100$, इसलिए $P = 100000$।
