Answer 1

$\Huge\bf\underline{\underline{\purple{Answer}}}$

Principal=64000

Rate=7.5%p.a

Time=3years

Where r is the rate and t is the time.

$\large\sf\implies{\underline{\red{CI \: = 64000 \: \: (1 + \frac{7.5}{100})^{3} - 64000 }}}$

$\large\sf\implies{\underline{\orange{64000 (1 + \frac{75}{1000} )^{3} - 64000 }}}$

$\large\sf\implies{\underline{\blue{64000 \: ( \frac{1 + 3}{40} )^{3} - 64000}}}$

$\large\sf\implies{\underline{\green{64000 \: (\frac{43}{40})^{3} - 64000 }}}$

$\large\sf\implies{\underline{\pink{64000 \times \frac{43}{40} \times \frac{43}{40} \times \frac{43}{40} - 64000 }}}$

$\large\sf\implies{\underline{\red{43 \times 43 \times 43 - 64000 }}}$

$\large\sf\implies{\underline{\orange{79507 - 64000}}}$

CI will be 15507 rupees.

Hope it's help you.
