    A reduction of 25% in the price of sugar enbles a man to buy \[7\frac{1}{2}\,kg\] more sugar for Rs. 360. The original price per kg of sugar was

    A)  Rs. 16 

    B)  Rs. 18

    C)  Rs. 20             

    D)  Rs. 25

    Correct Answer: A

    Solution :

    Let the original price of sugar \[~=Rs.\,x/kg\] \[\therefore \] New price of sugar \[=x\times \frac{75}{100}\]             \[=Rs.\frac{3x}{4}\] According to the question,             \[\frac{360}{\frac{3x}{4}}-\frac{360}{x}=\frac{15}{2}\] \[\Rightarrow \]   \[\frac{480}{x}-\frac{360}{x}=\frac{15}{2}\] \[\Rightarrow \]   \[\frac{120}{x}=\frac{15}{2}\] \[\Rightarrow \]   \[x=\frac{120\times 2}{15}\]             \[=Rs.\,\,\text{kg}\]
