Answer 2

Answer:

$\huge\mathcal{ solution}$

Here , P = 33,280 , R = 12½ = 25/2 , n = 3 , A = ?

We know that -

$\mathcal\pink{ A \: = p(1 + \frac{r}{100} {)}^{n} } \:$

$\mathcal\orange{ =33280(1 + \frac{25}{200} {)}^{3} }$

$\mathcal\green{ = 33280(1 + \frac{1}{8} {)}^{3} }$

$\mathcal\red{ = 33280( \frac{9}{8} {)}^{3} }$

$\mathcal\purple{ A = 33280 \times \frac{9}{8} \times \frac{9}{8} \times \frac{9}{8} }$

$\huge\mathcal\blue{ = \: rs \: 47385 }$

Compound interest = Amount - Principal

$\mathcal\pink{ = rs \: 47385 \: - \: 33280}$

$\huge\mathcal\purple{ = rs \: 14105}$

Hence , the required amount is ₹ 47,385 and compound interest is ₹ 14,105 .
