    C)  97      

    D)         99  

    Correct Answer: D

    Solution :

    Arranging the given numbers in ascending order, we get 75.75.80, 94, 96, 98, 100, 102,180,200, 270, 610 Now, number of terms =12, which is even. \[\therefore \] Median = Average of \[{{\left( \frac{12}{2} \right)}^{th}}\] and \[{{\left( \frac{12}{2}+1 \right)}^{th}}\] term = Average of 6th and 7th term \[=\left( \frac{98+100}{2} \right)=\frac{198}{2}=99\]
