    A) 2 : 1                             

    B) 1 : 2      

    C) 4 : 1                             

    D) 1 : 4

    Correct Answer: D

    Solution :

    Let x kg of sugar costing Rs. 20/kg and y kg of sugar costing Rs. 15/kg are mixed. According to the question,             \[20x+15y=16(x+y)\] \[\Rightarrow \]   \[20x+15y=16x+16y\] \[\Rightarrow \]   \[20x-16y=16y-15y\]      \[\Rightarrow \]   \[4x=y\] \[\therefore \]      \[\frac{x}{y}=\frac{1}{4}\]
