(B) Let the principal sum be $P$ and the rate of interest be $R = x \%$. Given that the time $T$ (in years) is equal to the rate $R$,so $T = x$.Simple Interest $(SI)$ is given as $\frac{16}{25} P$.The formula for Simple Interest is $SI = \frac{P 	imes R 	imes T}{100}$.Substituting the values: $\frac{16}{25} P = \frac{P 	imes x 	imes x}{100}$.Dividing both sides by $P$: $\frac{16}{25} = \frac{x^2}{100}$.$x^2 = \frac{16}{25} 	imes 100$.$x^2 = 16 	imes 4 = 64$.$x = \sqrt{64} = 8$.Thus,the rate per cent is $8 \%$.

Simple interest on a certain sum is $\frac{16}{25}$ of the sum. If the rate per cent and time (in years) are equal,then the rate per cent is:
