Answer 2

Answer:

2.1 rs

Step-by-step explanation:

sum= 10rs, Rate= 10% per annum, time = 2 years

Amount=

$p{( 1 + \frac{r}{100} )}^{n} \\ = 10 {(1 + \frac{10}{100} )}^{2} \\ = 10 {( \frac{11}{10}) }^{2} \\ = 10 \times \frac{121}{100} \\ = \frac{121}{10} = 12.1$

CI = Amount- Principal

= 12.1-10= 2.1
