Question 1129636
<pre>
Obviously you meant SIMPLE interest, not compound interest.

I = P&#8729;R&#8729;T

I = 3600
P = 60000
T = 120/360 = 1/3
R = ?

3600 = 60000&#8729;R&#8729;(1/3)

Multiply 60000 by 1/3, get 20000

3600 = 20000&#8729;R

Divide both sides by 3600

3600/20000 = R

0.18 = R

Answer 18% simple interest.
