Question

calculate the compound interest that gokal will get by investing Rs 100 for 3 years at the rate of 10% per annum​

Answer 1

Answer:

Hence value of compound interest will be 33.1

Step-by-step explanation:

In context to questions asked

We have to determine the value of compound interest

As per questions

We have

P = Rs 100

Time = 3 yr

Rate = 10%

As we know that

Amount = Principal + CI

$Amount = p ({1 + \frac{r}{100} )}^{t}$

So putting the given values for determining the amount

We will get

$Amount = 100 \times ( {1 + \frac{10}{100} })^{3} \\ = > 100 \times ( { \frac{110}{100} })^{3} \\ = > 100 \times ( \frac{11}{10}^{3} ) \\ = > \frac{100 \times 11 \times 11 \times 11}{10 \times 10 \times 10} \\ = > \frac{1331}{10} \\ = > 133.1 \: rs$

Hence value of compound interest will be

$133.1 - 100 = 33.1 \: rs$
