Answer 1

Answer:

$\huge \sf \fbox\orange{A}\fbox\pink{n}\fbox\blue{s}\fbox\red{w}\fbox \purple{e}\fbox\red{r}$

SI = PRT/100

SI = 30000 × 3 × 10/100

SI = 300 × 3 × 10

SI = 9000

Now

Amount = P × (1 + R/100)ⁿ

Amount = 30,000 × (1 + 10/100)³

Amount = 30,000 × (100 + 10/100)³

Amount = 30,000 × (110/100)³

Amount = 30,000 × (11/10)³

Amount = 30,000 × 11/10 × 11/10 × 11/10

Amount = 30 × 11 × 11 × 11

Amount = 39,930

Now

CI = A - P

CI = 39,930 - 30,000

CI = 9,930

Difference = 9930 - 9000

Difference = 930
