There are 120 boats in marina.

Step-by-step explanation:

Let x be the total number of boats in the marina.

As per given , Number of white boats = $\dfrac{5}{6}x[\tex]Number of blue boats = [tex]\dfrac{2}{5}(x-\dfrac{5}{6}x)=\dfrac{2}{5}(\dfrac{x}{6})=\dfrac{x}{15}[\tex]Number of red boats = [tex]x-\dfrac{5}{6}x-\dfrac{x}{15}[\tex][tex]=x(\dfrac{30-25-2}{30})=x(\dfrac{3}{30})=\dfrac{x}{10}$
