Compound interest on the given sum............

➤ Formula :-

➤ Solution :-

$\dashrightarrow \sf \frac{80000 \times 3 \times 3}{100} + 80000$

$\dashrightarrow \sf \frac{ \cancel{80000} \times 3 \times 3}{ \cancel{100}} = 800 \times 3 \times 3$

$\dashrightarrow \sf800 \times 3 \times 3 + 80000$

$\dashrightarrow \sf7200 + 80000$

$\dashrightarrow \sf87200$
