==================================

Let the principal be P.

T (time) =5 years [GIVEN]

R (rate) = 5% [GIVEN]

A = P + I = 650

=> I = (A - P) = (650 - P)

Now, we know the formula to calculate the original sum of money (PRINCIPAL).

So, P = (I × 100)/(R × T)

=> P = { (650-P) × 100 } / (5×5)

=> P = (6500-10P)/3

=> 3P + 10P = 6500

=> 13 P = 6500

=> P = Rs. 500
