Q: Three blue chips are in a jar which is 10% of the entire chips. If 50% of the chips are white and the rest are green, how many green chips are there?
A: 10% + 50% = 60% of the chips in the jar are not green. So, 100% - 60% = 40% of the chips are green. There are 40% / 10% = 4 sets of 10% to make 40%. Hence, there are 3 chips x 4 sets = 12 green chips. The answer is 12.
Question: Yvonne and Janna were writing their 1000-word pair research paper. Yvonne was able to write 400 words while Janna wrote 150 more words than Yvonne. When they edited their paper, they removed 20 words and added twice as many words as they removed. How many more words should they add to reach the research paper requirement?
Answer: Janna wrote 400 + 150 = 550 words. Together, they wrote 400 + 550 = 950 words. They have 950 - 20 = 930 words left after omitting 20 words. Then 20 x 2 = 40 words were added during the editing. Overall, they have 930 + 40 = 970 words. Thus, they should add 1000 - 970 = 30 more words. The answer is 30.

Question: Bob is going to put in a vegetable garden on his property. It's going to be in one of the back corners of his land. He wants the width of the garden to be about an eighth of the width of his property, and the length to be a tenth of the length of his property. His land is 1000 feet wide and 2250 feet long. How many square feet is his garden going to be?
Answer: The width of his garden is going to be 1000 / 8 = 125 feet. The length of his garden is going to be 2250 / 10 = 225 feet. So the area of his garden is going to be 125 X 225 = 28125 square feet. The answer is 28125.
Q: Henley bought 300 candies and shared them with her two brothers. However, they realized 40% of them were sour, and they had to separate those out. If they then shared the good candies equally, how many candies did each get?
A:
If the number of candies was 300, and 40% percent were sour, then there were 40 / 100 * 300 = 120 sour candies. The number of good candies was 300 - 120 = 180. The number of people who received candy is Henley, 1 + 2 brothers = 3 people. if they divided the good candies equally, each person got 180 / 3 = 60 candies. The answer is 60.
