    A)  \[4:6:5\]          

    B)  \[4:5:6\]

    C)  \[16:24:25\]        

    D)       None of these

    Correct Answer: D

    Solution :

     Shalini's equivalent      =Rs. \[\left( 80000\text{ }\,\,\,\,12+100000\text{ }\,\,\,\,12 \right)\]      = Rs. \[\left( 960000\text{ }+\text{ }1200000 \right)\]       = Rs. \[2160000\] Nalini's equivalent capital for 1 month      =Rs. \[\left( 80000\text{ }\,\,\,\,12+50000\text{ }\,\,\,12 \right)\]       = Rs. \[\left( 960000\text{ }+\text{ }600000 \right)\]       = Rs.1560000 \[\therefore \] Ratio of the profit       \[=\text{ }2160000\text{ }:\text{ }1560000\]        \[=216:\text{ }156=18:\text{ }13\] \[\therefore \] Nalini's share = Rs. \[\left( \frac{13}{13+18} \right)\,\,\,93000\] = Rs. \[\left( \frac{13}{31}\,\,\,\,93000 \right)\,\,\] = Rs. 39000
