<human>:  Out of the 200 students in a class, thirty percent like the color blue. Among the remaining students who don't like the color blue, 40% like the color red, and the rest like the color yellow. Calculate the combined number of students who like the color yellow and the color blue.
<bot>: How many students like the color blue? ** The number of students who like the color blue is 30/100*200 = <<30/100*200=60>>60
How many students don|t like the color blue? ** Out of the 200 students in the class, 200-60 = <<200-60=140>>140 don't like the color blue.
How many students like the color red? ** Among the students who don't like the color blue, 40/100*140 = <<40/100*140=56>>56 students like the color red.
How many students like the color yellow? ** If the rest of the students like neither blue nor red and only like the color yellow, their number is 140-56 = <<140-56=84>>84
How many students like the color yellow and the color blue? ** The total number of students who like the color yellow and those who like the color blue is 84+60 = <<84+60=144>>144
