In a certain time, the ratio of a certain Principal and the simple interest obtained from it are In the ratio 10:3 at 10% interest per annum. The number of years the money was invested is
Let the principal sum = Rs. 10 and interest at 10% = Rs. 3
Let time period = $$t$$ years
=> Simple interest = $$\frac{P\times R\times T}{100}$$
=> $$\frac{10\times10\times t}{100}=3$$
=> $$t=3$$ years
=> Ans - (B)
