Question

6. Find the rate of simple interest if
• (i) the interest on 4000 for 3 years is 600.
(ii) the interest on 1000 for 5 years amounts to 300. ​

Answer 1

${\huge{\bold{\blue{HeyMate}}}}$

• Here is your answer...

Given,

Principle = 4000

Time = 3 years

Interest = 600

Simple Interest = 600

Rate = R (let assume as R)

$600 = \frac{P \times R \times T}{100}$

$600 = \frac{4000 \times R \times 3}{100}$

$600 = 40 \times 3 \times R$

$\frac{600}{120} = R$

$5 = R$

hence Rate is 5%

Answer 2

• Here is your answer...

Given,

Principle = 4000

Time = 3 years

Interest = 600

Simple Interest = 600

Rate = R (let assume as R)

600 = \frac{P \times R \times T}{100}600=100P×R×T

600 = \frac{4000 \times R \times 3}{100}600=1004000×R×3

600 = 40 \times 3 \times R600=40×3×R

\frac{600}{120} = R120600=R

5 = R5=R

hence Rate is 5%
