Answer:
Step-by-step explanation:
The formula of simple interest is as below.
I = P*R*T÷100
Where I is interest.
P is Principle amount
R is rate of interest
T is time in years.
From your question, money becomes 3 times, it means, interest itself is Twice of P here. So,
2P = P*R*20/100
Hence R = 2P*100/20P = 10%
