Question

Answer 1

$<b> heyaaa user!!!$

Principal = Rs 12800

$\bold{rate \: = \frac{15}{2} \%}$

Time = 1 year

On finding compound interest semi-annually, we have to make 2 times the time and half the rate%.

$\bf{amount = p(1 + { \frac{r}{100}) }^{t}}$

$\bf{a = 12800(1 + { \frac{1/2×15/2}{100} })^{2} }$

$\bf{a = 12800( 1.0 375) }^{2}}$

$\bf{a = 12800 \times 1.0764}$

a = Rs 13778

Compound interest = Amount - principal

= 13778 - 12800

= 978

Compound Interest = Rs 978

Amount = Rs 13778
