Answer 2

$\Large\bf{✯Answer✯}$

$\bf{Given,}$

$\bf{➟Principal\:= ₹4500}$

$\bf{➟Time\:=2 \frac{1}{2}} \: years \\ = \frac{5}{2} \: years$

$\bf{➟Simple\:interest \: = \frac{p \times t \times r}{100} } \\ = \: \frac{4500 \times 5 \times 23}{100 \times 2 \times 3} \\ = \: 862.5$

❥Therefore the simple interest is ₹862.5

Now, lets find the Amount

$\large\sf{➟Amount\:=\:p \: + \: s.i}$

$= 4500 + 862.5 \\ = 5362.5$

Therefore the amount is ₹ 5362.5

❥Answer

The simple interest (s.i) is ₹ 862.5

and the amount is ₹ 5362.5
