Question

Calculate the simple interest of Rs 7000 in 2 years at the rate of 9 p.c.p.a?
​

Answer 1

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the Simple Interest.
• And to find the Simple Interest, we must use the formula of :

$\sf Simple \: Interest = \dfrac{p \times r \times t}{100}$

• Here, we have to multiply Principal, Rate, and Time first. Then, we must divide it by 100.

Given :

• Principal = Rs. 7000
• Rate = 9%
• Time = 2 years

To find :

• Simple Interest

Solution :

$\sf Simple \: Interest = \dfrac{p \times r \times t}{100}$

                      $\sf = \dfrac{7000 \times 9 \times 2}{100}$                    

                      $\sf = \dfrac{70 \times 9 \times 2}{1}$

                      $\sf = \dfrac{70 \times 18}{1}$

                      $\sf = \dfrac{1260}{1}$

                      = 1260

Therefore, Simple Interest is Rs. 1260.

                     

                     

Answer 2

$\large {\frak{\underline {\underline { Given :}}}}$

• Principal = Rs. 7000
• Time = 2 years
• Rate of interest = 9%

$\large {\frak {\underline {\underline { To \; find :}}}}$

• Simple interest

$\large {\frak {\underline {\underline { Solution :}}}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎$\small {\frak {\underline {\purple { \dag \; Formula \; to \; be \; used :}}}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

ㅤ‎ㅤ$\large {\boxed {\frak { Simple \; Interest = \dfrac { P \times R \times T}{100}}}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

$\implies \sf { S.I = \dfrac { 7000 \times 9 \times 2}{100}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

$\implies \sf { S.I = \dfrac { 7000 \times 18}{100}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

$\implies \sf { S.I = \dfrac { 126,000}{100}}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

$\implies \sf { S.I = 1260}$

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

Therefore, simple interest = 1260.
