    A shopkeeper bought an chair and sold it at a loss of 10%. If he had bought it for 20% less and sold it for Rs. 55 more, he would have had a profit of 40%. What is the cost price of chair?

    A)  Rs. 250

    B)  Rs. 200

    C)  Rs. 225            

    D)  Rs. 175

    Correct Answer: A

    Solution :

    CP = Rs. x SP\[=\left[ \frac{90}{100}\times x \right]=\text{Rs}\text{.}\left[ \frac{9}{10}x \right]\] New CP \[=\left[ \frac{80}{100}\times x \right]\]= Rs.\[\left( \frac{4x}{5} \right)\] Now, gain = 40% \[\therefore \]New Selling price \[=\left( \frac{140}{100}\times y\frac{4x}{5} \right)\] = Rs. \[\left( \frac{28x}{5} \right)\] \[\therefore \]      \[\frac{28x}{25}-\frac{9}{10}x=55\]\[\Rightarrow \]\[x=250\]
