    B)  Rs. 170

    C)  Rs. 175.50       

    D)  Rs. 180

    Correct Answer: C

    Solution :

    Let the quantities of tea worth Rs. 126, Rs. 135 and Rs. x per kg are y kg, z kg and 2y kg respectively. \[\therefore \]      \[\frac{126y+135y+2xy}{4y}=153\] \[\Rightarrow \]   \[261y+2xy=612y\] \[\Rightarrow \]               \[2x=351\] \[\Rightarrow \]               \[x=175.50\]
