What grade level do you go to?
Thank you for posting the video. At 9:01 I'm not understanding how you determined zero from reading the question.
Since the questions says all of the students went to one of the three cities, so they all belong to one of the three circles/cities (A, B and C). Therefore, no one is outside the three circles/cities.
thanks sir...you are the best
Excellent

Hi sir, i guess you can use the last statement Aonly+Bonly+Conly =38 after writing x, 19-x, 28-x and 31-x. Note that all sectors add up to 100, thus, 38+x+19-x+28-x+31-x=100, then solve for the value of x. X=8
yes, you can. Good!
why do you use the 3x for dividing ?
Thanks bro
