Let's assume the principal amount be $P.$
After getting an annual rate of interest as $10\%$ which is compounded annually, $5$ years later the amount should be $10,00,000$
So, $P\left(1 + \dfrac{10}{100}\right)^5 = 10,00,000$
$\quad \implies P\left(\dfrac{11}{10}\right)^5 = 10^6$
$\quad \implies P = \dfrac{10^6 * 10^5}{(11)^5} = \dfrac{10 ^ {11}}{11^5}$
$\quad P = 620921.323 \approx 621000$
