Answer 1

Answer:

Let the sum be x

We are given that simple interest earned on a certain sum in 5 years is 30% of the sum

So, simple interest =\frac{30}{100}x=0.3x

100

30

x=0.3x

Time - 5 years

Let rate of interest be r

Simple interest = \frac{P \times R \times T}{100}

100

P×R×T

0.3x=\frac{x \times r \times 5}{100}0.3x=

100

x×r×5

0.3=\frac{r \times 5}{100}0.3=

100

r×5

6=r6=r

Hence the rate of interest is 6%
