Answer 1

Heyy!!✋✋

Here is your answer ⤵⤵

Formula for calculating compound interest -

$p(1 + { \frac{r}{100} })^{t}$
P =4000
R=7.5
Time=2

$4000(1 + { \frac{7.5}{100}) }^{2} \\ \\ 4000(1 + { \frac{75}{10 \times 100} }) ^{2} \\ \\ 4000(1 + { \frac{3}{40} })^{2} (simplifying \: the \: terms) \\ \\ 4000( { \frac{43}{4 0} }) ^{2} \\ \\ 4000 \times \frac{43}{40} \times \frac{43}{40} \\ \\ = 4622.5$
CI = 4622.5-4000
=₹622.5
