Question

Find rate when (A) principal=RS=1650, Time=2years ,
Simple interest=RS 82.50

Answer 1

Answer:

Simple Interest=Principal*rate*time/100

82.50=1650*rate*2/100

rate=82.5/33=2.5

Answer 2

Your answer:-

$rate= \frac{simple \: interest \: \times 100}{principal \times time}$

$rate = \frac{82.50 \times 100}{1650 \times 2}$

$rate = \frac{8250}{1650 \times 2}$

$rate = \frac{825 }{165 \times 2}$

$rate = \frac{825}{330}$

rate = 2.5% p.a.

Therefore, the rate is 2.5% p.a.
