Question

Find the simple interest and amount for Rs 870 in 8 years ,the rate of interest 2 .5 % per annum ?​

Answer 1

as we know

$simple \: inte. = \frac{p \times r \times t}{100}$

$simple \: interest = \frac{870 \times 2.5 \times 8}{100}$

$simple \: inte. = rs \: 174$

and we know,

$amount = p \: + simple \: inte.$

$amount \: = 870 + 174$

$amount = rs \: 1044$
