Answer:
Answer is 11%
Step-by-step explanation:
Principle Amount=12,000=P
Final Amount=36,000=F
T=9years
Rate=?
>Simple interest=Final Amount - Principle Amount
=36,000 - 12,000
=24,000
Now, we know that
Simple interest=P× R×T by 100
12,000=12,000×R×9 by 100 (12,000 will be canceled)
R=100 by 9=11%
Therefore, the rate per annum is 11%
