    A)  37                         

    B)         39

    C)  41                         

    D)         51  

    Correct Answer: D

    Solution :

     The ratio of men to women is\[5:3\]. Hence, the number of men divided by the number of women must\[\frac{5}{3}\]. The number of men is\[85\]. Let \[x\] be the number of women in the party. \[\therefore \]  \[\frac{85}{x}=\frac{5}{3}\] \[\Rightarrow \]                 \[x=\frac{85\times 3}{5}=17\times 3=51\] \[\therefore \]Number of Women\[=51\].
