We don't know the principal amount

So, 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, $P(1 + \dfrac{10}{100})^5$ = 10,00,000

$P(\dfrac{11}{10})^5$ = $10^6$

$P$ = $\dfrac{10^6 * 10^5}{(11)^5}$

$P$ = $\dfrac{10 ^ {11}}{11^5}$

$P$ = 620921.323 ≅ **621000 Option B)**
