Answer:
The interest rate = 6 %
Explanation:
We have I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.
Here principal, p = 200 $
Number of years , t = 3
Interest received, I = 36$
We need to find rate of interest.
Substituting
36 = 200 x r x 3
r =
= 0.06 = 6%
The interest rate = 6 %
