The simple interest of an amount is $\frac{16}{25}$ of the principal. Find the rate % PA, if the time and rate both are numerically equal.

8 %

4 %

12 %

16 %

✅ Correct Option: 1

Given SI $= \frac{16}{25}P$ and rate $=$ time $= n$ . Using SI $= \frac{PRT}{100}$ : $\frac{16}{25}P = \frac{P \cdot n \cdot n}{100}$ . So $\frac{n^2}{100} = \frac{16}{25}$ , giving $n^2 = 64$ , $n = 8$ . Rate $= 8\%$ .
