Question

calculate the compound interest on rs 2500 for two years if the rate is 9% per annum compounded annualy​

Answer 1

Answer :-

Given :-

• Principal = Rs. 2500
• Time = 2 years
• Rate of interest = 9% p.a.

To Find :-

• Compound interest

Solution :-

$\sf Amount = P \Big(1 + \dfrac{R}{100}\Big)^n$

$\implies\sf A = 2500 \times \Big(1 + \dfrac{9}{100}\Big)^2$

$\implies\sf A = 2500 \times \Big(\dfrac{109}{100}\Big)^2$

$\implies\sf A = 25\cancel{00} \times \dfrac{11,881}{100\cancel{00}}$

$\implies\sf A = \cancel{25} \times \dfrac{11881}{\cancel{100}}$

$\implies\sf A = \dfrac{11881}{4}$

$\implies\sf A = 2970.25$

Amount = Rs. 2970.25

Compound interest = Amount - Principal

= 2970.25 - 2500

= 470.25

Compound interest = Rs. 470.25
