If we have 100 tourists, 30 of them both have beverages and ride bicycles.
If 60% of the tourists riding bicycles do not have beverages, 40% of the tourists riding bicycles is 30.

The total members having bicycles can be calculated as follows:

If $$40$$% is $$30$$ and $$100$$% is x, then x = $$30*\frac{100}{40} = 15*5 = 75$$

Therefore, 25 tourists have no bicycles and this represents $$\frac{25}{100}$$ or $$25$$% of the tourists(Option C)
