Question

4. Find the sum of money on which the interest equals
(1) 5700 in 3 years at the interest rate of 4% per annum.
​

Answer 1

Answer:

6348

Step-by-step explanation:

5700×3×4/100 = 57×3×4= 57×12=648 is the interest

Amount = 5700+648 = 6348

Answer 2

Given

• Interest = ₹ 5700
• Time (t) = 3 Years
• Rate (r) = 4%

Formula Used

$\maltese \ {\large{\pmb{\boxed{\sf\gray{ Interest_{(Simple)} = \dfrac{P \times R \times T}{100} }}}}}$

Where as:

• P = Principal
• R = Rate
• Time = Time

Explanation:

❍ Let the Principal be x and With the help of all given data we can find the desired results as:-

$\maltese {\underline{\pmb{\sf{ According \ to \ Question : }}}} \\ \\ \colon\implies{\sf{ 5700 = \dfrac{x \times 4 \times 3}{100} }} \\ \\ \\ \colon\implies{\sf{ \dfrac{ \cancel{5700} \times 100}{ \cancel{3} \times 4 } = x }} \\ \\ \\ \colon\implies{\sf{ \dfrac{ \cancel{1900} \times 100}{ \cancel{4} } = x }} \\ \\ \\ \colon\implies{\sf{ x = 475 \times 100 }} \\ \\ \\ \colon\implies{\large{\pmb{\boxed{\sf\purple{ x =Rs. \ 47500 }}}}}$

Hence,

$\\ {\underline{\sf{ The \ Principal \ of \ the \ transaction \ is \ Rs. \ 47500 }}}$
