Question

Find the CI on RS 2000 at 10 % per annum for 2 year​

Answer 1

Given :

• P = Rs 2000

• Rate ( R) = 10%

• n = 2 .

To find :

• Compound interest :

Solution :

As we know that :

$\star \boxed{\bold{ Amount = p(1 + \dfrac{R}{100} ) {}^{n} }}$

Put the given values :

$\implies \: Amount = 2000 {(1 + \dfrac{10}{100} })^{2} \\ \\ \implies \: Amount = 2000(1 + \dfrac{1}{10} ) {}^{2} \\ \\ \implies \: Amount \: = 2000 \times \frac{121}{100} \\ \\ \implies \: Amount \: = 121 \times 20 \\ \\ \implies \: Amount \: = 2420$

• Amount = Rs 2420 .

Now ,

• C• I = Amount - principal

=> CI = 2420 - 2000

=> C• I = 420

Hence , C • I is Rs420.
