    A person bought two bicycles for Rs.1600 and sold the first at 10% profit and the second at 20% profit. If he sold the first at 20% profit and the second at 10% profit, he would get Rs.5 more. The difference of the cost price of the two bicycles was:

    A)  Rs.50             

    B)       Rs.40

    C)  Rs.25             

    D)       Rs.75

    Correct Answer: A

    Solution :

     If the C.P. of first cycle be Rs. x, then C.P. of second cycle \[=Rs.\,(1600-x).\] \[\therefore \]    \[\frac{x\times 120}{100}+\frac{(1600-x)\times 110}{100}\] \[-\frac{x\times 110}{100}-\frac{(1600-x)\times 120}{100}=5\] \[\Rightarrow \]\[12x+17600-11x-11x-19200+1\,2\,x=50\] \[\Rightarrow \]\[2x=50+19200-17600\] \[\Rightarrow \] \[2x=1650\Rightarrow x=825\] C.P. of second cycle \[=1600-825=Rs.\text{ }775\] Difference \[=825-775=Rs.\text{ }50\]
