Let say the c.p is x
Raj sold his scooter to rahim at 8% loss, so {x-(8% of X) = (23x)/(25)

rahim in turn sold the same scooter to prem at 5%,
now lets say rahim brought the scooter at price y
and sold it by 5% gain so, y+(5% of y)= 21y/20

prem paid ₹14490 so the eq is

(21y/20) = 14490 

and as we can see, y=(23x)/(25)=13800 rupees    so


find the x which will be the c.p and then put the value of x on (23x)/(25) to get the sell price.
