Solution:-
people like honey means only honey or both honey and sugar=60%=60
People like sugar means only sugar OR BOTH honey and sugar=40%=40
people like both honey and sugar=30%=30
So people like only honey+people like only sugar+ People like both + people like neither honey and sugar =100
we have (60-30)+(40-30)+(30)+x=100
=30+10+30+x=100
=x=100-70
=x=30
