conversations.value: The number of students who like the color blue is 30/100*200 = 60
  Out of the 200 students in the class, 200-60 = 140 don't like the color blue.
  Among the students who don't like the color blue, 40/100*140 = 56 students like the color red.
  If the rest of the students like neither blue nor red and only like the color yellow, their number is 140-56 = 84
  The total number of students who like the color yellow and those who like the color blue is 84+60 = 144
