    D)  3240

    E)  3136

    Correct Answer: E

    Solution :

     In the year 2013, Male population = 6x Female population = 7x According to the question, In the year 2014, \[\frac{6x\times 115}{100}+\frac{7x\times 112}{100}=5896\] \[\Rightarrow 690x+784x=589600\] \[\Rightarrow 1474x=589600\] \[\Rightarrow x=\frac{589600}{1474}=400\] \[\therefore \] Female population in the year 2014 \[=7x\times \frac{112}{100}\] \[=\frac{7\times 400\times 112}{100}=3136\]
