Answer 1

Answer:

$\huge \color{orange}{ \underline{SoLuTiOn \implies}}$

We have : P = ₹ 16000, S. I. = ₹2560, Time = 2 years.

Let the rate be R% per annum . Then

$R = \frac{100 \times S. I. }{P \times T}$

$( \frac{100 \times 2560}{16000 \times 2} ) p.a.$

$= 8\%p. a.$

$\textbf \color{red}Hence, the required rate is 8\% \: per \: annum$
