Answer 1

Answer:

$\huge\mathcal{\fcolorbox{aqua}{azure}{\red{given}}}$

• calculate the difference between c.i and s.i on rs 4000 at 8% per annum in 2year .

$\huge\mathcal{\fcolorbox{aqua}{azure}{\red{to \: find}}}$

For ,

N=2years

R=8 % 

P=Rs4,000

We have S.I.

$= \frac{pnr}{100}$

$\frac{4000 \times 2 \times 8}{100}$

$= rs.640$

And on interest being compounded for 2  years and R=8 %, 

Amount=P

$(1 + \frac{r}{100} )n$

N=4,000×(1+100/8)²

=4,000×1.08×1.08

=Rs4,665.60

So, C.I.=A−P=4,665.60−4,000

=665.60

And required difference C.I.=S.I.

=665.60=640

=Rs25.60
