Question

Calculate the simple and compound interest at 5% annual rate on Rs1260/- after 2 year

Answer 1

Answer:

Simple interest = ₹126 ;

Compound interest = ₹129.15

Step-by-step explanation:

$\bold{\underline{\underline{Formula:}}}$

$SI\:=\:\Large{\frac{P\:×\:T\:×\:R}{100}}$

= $\Large{\frac{1260\:×\:2\:×\:5}{100}}$

$SI\:=\:\large{\boxed{126}}$

$\bold{\underline{\underline{Formula:}}}$

$A\:=\:P{(1\:+\:\large\frac{r}{100})}^{n}$

= $1260{(1\:+\:\large\frac{5}{100})}^{2}$

= $1260{(\large\frac{105}{100})}^{2}$

= $1260{(\large\frac{21}{20})}^{2}$

= $1260\:×\:\large\frac{21}{20}\:×\:\large\frac{21}{20}$

$A\:=\:1389.15$

$C.I\:=\:A\:-\:P$

$C.I\:=\:1389.15\:-\:1260$

$C.I\:=\:\large{\boxed{129.15}}$
