Answer 1

The amount after simple interest is given by

A=P(1+rt)

Where P is principal amount

r is interest rate in decimal

t is number of years

$given , \: A=Rs.2502.50, r = \frac{27 }{2 \times 100} ,t = 4$

$2502.5=p(1 + \frac{27}{400} \times 4)$

$= > 2502.5=1.54p$

$= > P= Rs.1625$

$\therefore \: the \: sum \: is \: rs.1625$
