Question

Anuj invests ₹2500 at a rate of 7 (1/2)%. What will his balance at the end of three years? *​

Answer 1

Answer:

$principle = ₹2500 \ rate \: of \: interest = 7 \frac{1}{2}%</p><p>$

$[tex]time = 3 \: years$

$so \: we \: have \: to \: find \: simple \: interest \: and \: amount$

$s.i \: {simple \: interest} = \frac{prt}{100}$

[/tex]

$where \: p = principal \\ r = rate \: of \: interest \\ t = time$

$first \: we \: have \: to \: covert \: mixed \: rate \: of \: percentage \: to \: normal \: percent$

$on \: substituting \: the \: values \: we \: get,$

$= 7 \frac{1}{2} \: \: \: \: \% = \frac{7 \times 2 + 1}{2}$

$= \frac{14 + 1}{2}$

$= \frac{15}{2} \: \: \: \: \% = 7.5 \: \: \: \: \%$

$s.i = \frac{2500 \times 7.5 \times 3}{100}$

$si = \frac{56250}{100}$

$s.i = 562.5$

$amount \: = principal + simple \: interest$

$on \: substituting \: the \: values \: we \: get$

$amount = ₹2500 + ₹562.5$

$amount = ₹3062.5$

his balance at end of three years is ₹3062.5
