I have $50000000 with an interest of 20% investing it for 2years in the bank. How much will I have at the end of the 2 years

Kn = Ko * (1+p/100)^n

Ko = 50 000 000 $        p = 20 %         n = 2  years

Kn =$${\mathtt{50\,000\,000}}{\mathtt{\,\times\,}}{{\mathtt{1.2}}}^{{\mathtt{2}}} = {\mathtt{72\,000\,000}}$$  $

You will have  72 000 000 $ .
