    A man buys 4 tables and 5 chairs for Rs. 1000. If he sells the tables at 10% profit and chairs 20% profit, he earns a profit of Rs. 120. What is the cost of one table?

    A) Rs. 200

    B) Rs. 220

    C) Rs. 240             

    D) Rs. 260

    Correct Answer: A

    Solution :

    Let cost of 1 table be Rs. x and cost of 1 chair be Rs. y. \[4x+5y=1000\]                         ?(i)             Table                chair CP        \[4x\]                 \[5y\] SP        \[4x\left( 1+\frac{1}{10} \right)=\frac{44x}{10}5y\left( 1+\frac{1}{5} \right)=6y\] \[\because \]       \[\text{SP}-\,\,\text{CP}=\text{Profit}\] \[\therefore \]      \[\left( \frac{44x}{10}-4x \right)+6y-(4x+5y)=120\] \[\Rightarrow \]   \[\frac{4x}{10}+y=120\]                                   ?(ii) From Eqs. (i) and (ii), we get \[x=Rs.\,200\]
