My question is: 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. Your thoughts:

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. The final answer: 144.
