Answer 2

$\pmb{To \: find:}$

diya deposited 8000 rupees in a bank,which gives 10% interest compounded annually.after 2 years,she withdrawn 5000 rupees.after 1 year how much would she have in her account?

Answer:

Amount deposited =

$\sf \orange{\implies \: 8000 \: rupees}$

Amount in the account of Diya at the end of 2 years=

$\rm \red{ \implies \: P[1 + \frac{r}{100 }]^n}$

$\sf \purple{ \implies \: 8000[1 + \frac{10}{100} ] ^{2} }$

$\implies \bf\pink{8000[ \frac{110}{100} ^{2} ]}$

$\sf \implies \: 80 \cancel{00} \times \frac{11 \cancel0}{1 \cancel{00}} \times \frac{11 \cancel0}{1 \cancel{00}}$

$\sf \blue{{80 \times 11 \times 11}}$

$\sf \underline{\implies \: 9680}$

(After two years) amount withdrawed=

$\implies5000$

$\tt \green{\implies \: 9680 - 5000 = 4680}$

principle in the third year=4680

• P =4680
• r=10%
• n=1

$4680 \times [\frac{11 \cancel0}{1 \cancel{00}} ]$

$\implies \: 468 \times 11 = 5148$

So ,after 1 year she will have 5148 in her account.
