Answer 1

Answer:

Rate of Interest is $20\%$

Step-by-step explanation:

Given that

$I=\ 300, P=\ 3000$

and T=0.5 years

To find rate of interest

We have I=PRT

Therefore

$R=\frac{I}{PT}\times 100$

$R=\frac{300}{(3000)(0.5)}\times 100$

$=\frac{1}{10(0.5)}\times 100$

$=20\%$

Therefore $R=20\%$

Rate of Interest is $20\%$
