Distinct number of men, women and children have visited a park in a particular day. The number ofwomen visitors is 7 and the number of children who visited the park is maximum among all the visitors. If the ratio between the number of men and women is the same as the ratio between the number of women and children, then the total number of visitors to the park is

Number of men ,women and children are distinct number (given).

And number of women is 7.

Again,

number of men/number of women =

number of women/number of children.

So,number of men×number of children

=$$(number of women)^2$$

=$$7^2$$

=49.

But, 49 has three different factors 1,7 and 49.

as number of men, women and children are distinct, number of children or men can have either 49 or 1 as their value.

So,Total number of visitors were 

=49+7+1=57.

C is correct choice.
