Q: 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.
A: 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 answer is 144.

Answer: There are 35 / 5 = 7 light bulbs to every fifth. 7 * 3 = 21 lightbulbs in the kitchen are broken. There are 35 - 21 = 14 light bulbs in the kitchen that are not broken. There are 10 * 3 = 30 light bulbs in the foyer in total. There are 30 - 10 = 20 light bulbs in the foyer that are not broken. There are 14 + 20 = 34 light bulbs that are not broken in both the foyer and kitchen. The answer is 34.
