Question

find the amount and compound interest on 10000 for 1 and half years at 10% per annum compounded half yearly uddeshy interest be more than the interest he would get if it was compounded annually​

Answer 1

Answer:

Given:

n=1/2 yrs,

P=₹10000,

r=10%;

$a mount(a) = p \times (1 + \frac{r}{100}) {}^{n}$

let's put the values:

$= > a = 10000 \times (1 + \frac{10}{100} ) {}^{ \frac{1}{2} }$

$a = 10000 \times \sqrt{ \frac{100 + 10}{100} }$

remove 100 as 10²=100;

$a = 1000 \times \sqrt{110}$

$a = 10488rupees(approx)$

Compound interest (C.I.)=a-P

$c.i. = 10488 - 10000$

C.I.=₹488,
