Answer 1

Answer:

the answer is (a) rs.600

Step-by-step explanation:

Answer 2

Given

• $\rm\green{Principal =}$ 10,000
• $\rm\green{Time =}$ 3 Years
• $\rm\green{Rate\:of\:interest =}$ 2%

Solution

To find, the compound interest

Concept used :

${\boxed{\sf{P\times (1 + {\frac{ R}{100}})^{n} - P }}}$

$:\implies\sf{1000(1 + \frac{2}{100})^{3}}$

$:\implies\sf{1000(1 + \frac{100 + 2}{100})^{3}}$

$:\implies\sf{1000 × \frac{102}{100}× \frac{102}{100} × \frac{102}{100}}$

$:\implies\sf{102× 102 × \frac{102}{100}}$

$:\implies\sf{\frac{1061208}{100}}$

$:\implies\sf{10612.08}$

________________

$\rm\green{Amount =}$ $\sf{10612.08}$

$\rm\green{Principal =}$$\sf{10000}$

$\rm\green{So, CI =}$ $\sf{10612.08 - 10000}$

$\implies\:\sf{612.08\:Ans\:!}$
