Question

Write the formula of amount by compound interest​

Answer 1

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

Formula for Compound Interest :-

$\large \bigstar \:\boxed{\bf \blue{A= P\bigg(1 + \frac{r}{n} {\bigg)}^{nt}}}$

• A = final amount
• P = initial principal balance
• r = interest rate
• n = number of times interest applied per time period
• t = number of time periods elapsed

Answer 2

Formula is given :

${\underline{\boxed{\pmb{\sf{ A = P \bigg[ 1 + \dfrac{R}{400} \bigg]^{4n} }}}}}$
