Answer 2

$\large\sf\underline{Given:-}$

• $\sf\:Principal=Rs\:8000$

• $\sf\:Interest=Rs\:640$

• $\sf\:Time=4\:yrs$

$\large\sf\underline{To\:find:-}$

• $\sf\:Rate$

$\large\sf\underline{Solution:-}$

We know,

$\small{\underline{\boxed{\mathrm\pink{Rate=\frac{Interest \times 100}{principal \times time}}}}}$

$\sf\:⟹\:Rate=\frac{640 \times 100}{8000 \times 4}$

$\sf\:⟹\:Rate=\frac{64000}{32000}$

$\sf\:⟹\:Rate=\frac{64}{32}$

$\sf\:⟹\:Rate=\frac{2}{1}$

$\sf\:⟹\:Rate=2 \:percent$

$\small\fbox\red{↦\:Rate\:=\:2\:percent}$
