Example:
I = $184, T = 2 years and R = 2%, then find principle.

Solution:
Formula
I = PTR/100
Where I = Interest, P = Principal, T = Time and R = Rate or interest.

Therefore:
P = (I*100) / (TR)

Substituting the given values in the above formula.
P = (184 * 100) / (2 * 2)
P = 18400 / 4
P = $4,600
