Question

Sunita deposited 45,000 with bank for 2 years. If the rate of interest is 7/3 percent. find the amount she will get back from the bank.​

Answer 1

$\large\bf\underline {To \: find:-}$

• we need to find the amount, that Sunita get back from the bank.

$\huge\bf\underline{Solution:-}$

$\bf\underline{\red{Given:-}}$

• Principal = 45000
• Time = 2 years
• Rate = 7/3 %
• Amount = ?

We know that,

$\blue\bigstar\large \red { \rm \:Amount = p(1 + \frac{r}{100}) ^{n} }$

where,

• p = principal
• r = rate
• n = time

$\large\rightarrowtail \rm \: Amount = 45000 \big(1 + \frac{ \frac{7}{3} }{100} \big) {}^{2}$

$\large \rm \rightarrowtail \:Amount = 45000 \big(1 + \frac{7}{3} \times \frac{1}{100} \big) {}^{2}$

$\large\rm \rightarrowtail \:Amount =45000 \bigg(1 + \frac{7}{300} \bigg) {}^{2}$

$\large\rm \rightarrowtail \:Amount =45000 \bigg( \frac{300 + 7}{300} \bigg) {}^{2}$

$\large\rm \rightarrowtail \:Amount =45000 \bigg( \frac{307}{300} \bigg) {}^{2}$

$\large\rm \rightarrowtail \:Amount =45000 \times \frac{307}{300} \times \frac{307}{300}$

$\large\rm \rightarrowtail \:Amount =15 \times 307 \times \frac{307}{30}$

$\large\rm \rightarrowtail \:Amount =4605 \times \frac{307}{30}$

$\large\rm \rightarrowtail \:Amount = \frac{1413735}{30}$

$\bf \dashrightarrow 47124.5$

Hence,

Sunita get back Rs 47124.5 from the bank.

Answer 2

Question:

Sunita deposited 45,000 with bank for 2 years. If the rate of interest is 7/3 percent. find the amount she will get back from the bank.

Answer:

Sunita 47124.5 will get back from the bank.

To find:

the amount she will get back from the bank.

Solution:

Amount will get from the bank after 2 years .

$\implies \: Returns = P(1 + r) ^{t}$

P=Principal=45000

r=rate of interest=7/3

t=time=2years

$\implies \: Returns = 45000(1 + \frac{7}{300} ) ^{2}$

$\implies \: Returns =45000( \frac{307}{300} \times \frac{307}{300} )$

$\implies \: Returns =15 \times 307 \times \frac{307}{30}$

$\implies \: Returns =4605 \times \frac{307}{30}$

$\implies \: Returns = \frac{1413735}{30}$

$\implies \: Returns =47124.5$

therefore,

Sunita ₹47124.5 will get from bank.
