75 like coffee

Its obvious that $$x \leq 60$$ since the group which like both tea and cofee is a subset of the group that like tea, and the group that like coffee. Thus, $$x \leq Min\{\text{no. of coffe people}, \text{no. of tea people} \}$$ now from the venn diagram, $$60 + 75 -x \leq 100$$ |dw:1440479236933:dw|
