    The price of sugar is reduced by 20%. Now a person can buy 500 g more sugar for Rs. 36. The original price of the sugar per kilogram was

    A)  Rs. 14.40

    B)                     Rs. 18

    C)  Rs.  15.60                    

    D)  Rs. 16.50

    Correct Answer: B

    Solution :

    Let the original price of sugar = Rs. x/kg Reduced price of sugar = 80% of x \[=\frac{x\times 80}{100}\]= Rs. \[\frac{4x}{5}\]per kg \[\therefore \]      \[\frac{36}{4x}-\frac{36}{x}=\frac{1}{2}\] \[\Rightarrow \]   \[\frac{45}{x}-\frac{36}{x}=\frac{1}{2}\] \[\Rightarrow \]   \[\frac{9}{x}=\frac{1}{2}\] \[\therefore \]      \[x=9\times 2\]= Rs. 18 /kg
