    For Rs. 25,500. A furniture shop sells 3 computer tables and 5 chairs or 2 computer tables and 9 chairs. If one wants to buy a set of only 1 computer table and 1 chair, how much does he need to pay?

    A)  Rs.1.500          

    B)  Rs.5, 100

    C)  Rs. 6,000          

    D)  Rs.7, 500

    Correct Answer: D

    Solution :

     C.P. of 1 computer table = Rs. x C.P. of 1 chair = Rs. y According to the question, \[3x+5y=25500\]                    ..... (i) \[2x+9y=\text{ }25500\]                     ..... (ii) Clearly, cost of 1 computer table = cost of 4 chairs From equation (i). \[3\times 4y+5y=25500\] \[\Rightarrow \] \[17y=25500\] \[\Rightarrow \] \[y=\frac{25500}{17}=1500\] \[\therefore \] Cost of 1 computer table \[=4\times 1500=Rs.\,6000\] \[\therefore \]  Required answer \[=(6000+1500)=Rs.7500\]
