Dear fellow PRO people,

 

[glow=yellow]This is my first off-topic post and I have a problem I would like all of you to solve and I promise all that there is no trick to the question, just find the answer of the question. May the best win![/glow] :y: :Smile:

 

 

Among the Primary 6 students in a school, 60 like Mathematics, 50 like English and 42 like sports. 30 of them like both Mathematics and English, 20 of them like both English and sports and 35 of them like both Mathematics and sports. If 18 students like all three, how many have exactly one favourite subject?

 

Cheers now XDD
