Answer 1

Step-by-step explanation:

Given:

I = Rs. 280.

P = Rs. 56,000

T = 2 years

R = ?

Now,

$\pink{ i = \frac{p \times r \times t}{100}}$

$\pink{ 280 = \frac{56000 \times r \times 2}{100}}$

$\pink{280 = 560 \times 2r}$

$\pink{ \frac{280}{560} \times 2r}$

$\pink{\frac{1}{2} \times 2r}$

$\pink{ \frac{1}{2 \times 2} = r}$

$\pink{\frac{1}{4} = r}$

$\pink{r = 0.25\%p.a}$
