Answer 1

Answer:

Step-by-step explanation:

Compound amount will be

= 9600 ( 1 + 8/100)^3  = 9600 * ( 1 + 2/25)^3  = 9600 * (27/25)^3  = 9600 * 19683/15625  = Rs 12,093 (approx)

Compound Interest  = 12,093 - 9600  = Rs 2,493

Answer 2

Given:-

Principal =₹ 9600

Rate of interest = 8 % per annum

Time = 3/2 years.

To Find ;-

1. Amount

2. Compound Interest

Formula Used :-

$amount \: = p( {1 + \frac{r}{200} })^{2t} \\ compound \: interest = amount \: - principal$

Solution:-

$amount \: = p( {1 + \frac{r}{200} })^{2t} \\ = 9600( {1 + \frac{8}{200}) }^{2 \times \frac{3}{2} } \\ = 9600( {1 + \frac{1}{25} )}^{3} \\ = 9600( { \frac{26}{25}) }^{3} \\ = 9600 \times \frac{26}{25} \times \frac{26}{25} \times \frac{26}{25} \\ = 10798.69\\ compound \: interest = amount \: - principal \\ = 10798.69 - 9600 \\ = 1198.69$
