Question

what the sum of money will amount to rupees 1331 in 3 years at rate of 10% per annum compound interest​

Answer 1

Given:

The final amount is Rs 1331, the time period is 3 year, and the rate of 10% per annum compound interest​

To Find:

The sum of money (Principal amount) that will amount to rupees 1331 in 3 years at a rate of 10% per annum compound interest​

Solution:

According to the question,  

Amount (A) = 1331

Time (n) = 3 years

Rate (R) = 10%

$A = (1+\frac{r}{100})^{n}$

 

⇒  $1331 = P(1 +\frac{10}{100})^{3}$

 

⇒  $\frac{1331}{P}= \frac{110}{100} X \frac{110}{100} X\frac{110}{`100}$

 

⇒ $\frac{1331}{P} = \frac{1331}{1000}$

⇒ P = 1000

Hence, the sum of money that will amount to rupees 1331 in 3 years at a rate of 10% per annum compound interest is Rs 1000
