❇️♦️❇️

• Hence Rs 4000 amounts to Rs 5324 at 10% per annum compound interest in 3 years.

Answer 2

Answer:

Given that,

P=Rs. 4000

A=Rs. 5324

R=10%

Let the time be T year

We know that, for compound interest,

$A = P \times { 1 + \frac{r}{100} }^{t}$

$= 5324 = 4000 \times {(1 + \frac{10}{100} )}^{t}$

$= \frac{5324}{4000} = {1 + \frac{1}{10} }^{t}$

$= \frac{1331}{100} = {( \frac{11}{10} )}^{t}$
