The simple interest on a sum of money is 1/9th of the principal and the no. of years is equal to the rate percent p.a. Find the rate percent

A) 3% B)3+1/3%

C)10% D)1/3%

We know that

Where SI = Simple interest

 P = Principal

 R = Rate (in per cent per annum)

 T = Time period (in years)

According to the question, 

As the rate of interest can't have a negative value, therefore, we neglect the negative value of R.

Cheers!
