Answer 2

${\bold{\underline{\underline{Answer:}}}}$

${\bold{\therefore C.I=165.5\:rupees}}$

${\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\underline \bold{Given : } \\ \implies Principal = 500 \: rupees \\ \\ \implies Rate = 10\% \\ \\ \implies Time = 3 \: years \\ \\ \underline \bold{To \: Find : } \\ \implies Compound \: interest = ?$

• According to given question :

$\bold{Using \: formula \: of \: amount : } \\ \implies A= P \times (1 + \frac{R}{100} )^{T} \\ \\ \bold{Putting \: given \: values : } \\ \implies A = 500 \times (1 + \frac{10}{100} ) ^{3} \\ \\ \implies A = 500 \times (1 + \frac{1}{10} )^{3} \\ \\ \implies A= 500 \times ( \frac{10 + 1}{10} ) ^{3} \\ \\ \implies a = 500 \times \frac{121}{100} \\ \\ \implies A = \frac{500 \times 1331}{1000} \\ \\ \implies A= 0.5 \times 1331 \\ \\ \bold{\implies A = 665.5} \\ \\ \bold{for \: compound \: interest : } \\ \implies C.I= A - P \\ \\ \implies C.I= 665.5- 500 \\ \\ \bold{ \implies C.I= 165.5 \: rupees}$
