Answer 2

Solution

formula used

$\: \: \: \: \: \: \large{ \boxed{p_i = p(1 + \frac{r}{100} ) {}^{nt} }}$

given

p=28000 Rs

t=1 year

n=2 (cause compounded half-yearly )

putting values

$\implies p_i = 28000(1 + \frac{10}{100} ) {}^{2 \times 1} \\ \implies p_i = 28000( \frac{11}{10} ) {}^{2} \\ \implies p_i = 28000 \times \frac{121}{100} \\ \implies p_i = 280 \times 121 \\ \implies p_i = 33880 \: Rs$

therefore,the amount after 1 years= 33880 Rs

therefore, the compound interest is,

$= p_i-p\\ = (33880 - 28000) \: rs \\ = 5880 \: Rs$
