Answer 1

solution is in the pic .....

it's the basic method

Answer 2

Answer:

5410

Step-by-step explanation:

p= 20,000

r= 10%

t= 2 +½ yr

so,

$p(1 + \frac{r}{100} )^{n}$

= 20000(1+10/100)²

=24,200= A

again,

$\frac{prt}{100}$

=(24200×10×½)/100

=1210

si, total compound interest =( 24200-20000)+1210

=5410
