Question

find the ci on ₹2,500 at 10%per annum compounded annually for 2 years?​

Answer 1

Given :-  

• ₹2,500 at 10% per annum is compounded annually for 2 years  

To Find :-

• Find the Compound Interest ( CI )

 

Solution :-

~Here, we’re given the principal , rate and time for which the money is invested and we need to find the CI after the given time. We can easily find the amount by putting the values in it’s formula and then Compound Interest.  

Here,  

• The principal  ( P ) is Rs. 2,500  

• The rate ( R ) is 10 %  

• The time ( n )  is 2 years  

• The amount will be ( A )  

• Compound Interest be ( CI )  

As we know that formula of amount is ,  

$\sf \bullet \;\; A = P \bigg \{ 1 + \dfrac{R}{100} \bigg \}^{n}$

   

*By putting the values !  

$\sf \implies A = 2,500 \bigg \{ 1 + \dfrac{10}{100} \bigg \}^{2}$

$\sf \implies A = 2,500 \bigg \{ \dfrac{110}{100} \bigg \}^{2}$

$\sf \implies A = 2,500 \bigg \{ \dfrac{11}{10} \bigg \}^{2}$

$\sf \implies A = 2,500 \times \dfrac{11}{10} \times \dfrac{11}{10}$

 

$\sf \implies A = 25 \times 11 \times 11$

 

$\sf \implies A = Rs.\; 3,025$  

Finding the Compound Interest :-  

$\sf \bigstar \;\; CI = A -P$

$\sf \implies CI = 3025 - 2500$  

$\sf \implies CI = Rs.\; 525$

Therefore,  

• The CI will be Rs. 525
