Answer:

Rate of Interest is [tex]20\%[/tex]

Step-by-step explanation:

Given that

[tex]I=\$ 300, P=\$3000[/tex]

and T=0.5 years

To find rate of interest

We have I=PRT

Therefore

[tex]R=\frac{I}{PT}\times 100[/tex]

[tex]R=\frac{300}{(3000)(0.5)}\times 100[/tex]

[tex]=\frac{1}{10(0.5)}\times 100[/tex]

[tex]=20\%[/tex]

Therefore [tex]R=20\%[/tex]

Rate of Interest is [tex]20\%[/tex]
