Neha sold her old bicycle suffering a loss of 6%. If she had sold her bicycle for Rs. 90 more, she would have made a profit of 3%. Find the cost price of the bicycle.
Let C.P. be x and Orignal S.P. be y
⇒ loss% =C.P.−S.P.C.P.×100
6% loss
⇒6100=x−yx⇒yx=94100⇒y=94x100 and
3% loss
3100=(y+90)−xx⇒3x=100y+9000−100x
⇒103x=100(94x100)+9000
⇒9x=9000⇒x=Rs.1000
The cost price of the bicycle is Rs. 1000.
