Answer 1

$\huge{{ \mathfrak{ \underline{Given: }}}}$

• Principal = ₹4000
• Rate = 10%
• Time = 3/2 years = 3 half years

$\huge{ { \mathfrak{ \underline{ To \: find:}}}}$

• Compound interest

$\huge{ { \mathfrak{ \underline{Solution:}}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \underline{ \bullet \: \: \: { \rm{Formula \: to \: calculate \: compound \: interest}}}$

$\boxed{ \red{ \rm{ \large{ \underline{ci = p \times {(1 + \frac{r}{100} )}^{3} }}}}}$

According to question,

$\large{ \tt : \implies \: \: \: \: \: \: \: \: ci = 4000 {(1 + \frac{10}{100}) }^{3} }$

$\large{ \tt : \implies \: \: \: \: \: \: \: \: ci = 4000 {( \frac{11}{10}) }^{3} }$

$\large{ \tt : \implies \: \: \: \: \: \: \: \: ci = 4 \times 11 \times 11 \times 11}$

$\large{ \tt : \implies \: \: \: \: \: \: \: \: ci = 5324}$

$\huge{ { \mathfrak{ \underline{ Hence: }}}}$

The compound interest is ₹5324.
