The simple interest on a sum fora certain number of years, same as the rate percentage of the interest, is equal to the sum itself. The numberof years is equal to:
S.I = $$\frac{P \times r \times t}{100}$$
In this case S.I = P
and r = t
P =Â $$\frac{P \times t \times t}{100}$$
$$t^2 = 100$$ => t =10
So , the answer is option b)10.
