Open in App

Solution

Let CP =x, so S.P $= 1.2 x$
When CP is Rs. $100$ less,
$C P = x - 100$
$S P = 1.2 x - 100$
Now,
$1.2 x - 100 = 1.24 \times (x - 100)$
On solving , we get
$x = 600$
$C P = R s . 600$

Let CP =x=x, so S.P =1.2xWhen CP is Rs. 100 less,CP=x−100SP=1.2x−100Now, 1.2x−100=1.24×(x−100)On solving , we getx=600CP=Rs.600
