Reasoning and answer: There are 80 / 100 * 10 = 8 more purple flowers than yellow flowers. So in Mark's garden, there are 10 + 8 = 18 purple flowers. Purple and yellow flowers sum up to 10 + 18 = 28 flowers. That means in Mark's garden there are 25 / 100 * 28 = 7 green flowers. So in total Mark has 28 + 7 = 35 plants in his garden.
The answer: 35
What was the question?
Question: Mark has a garden with flowers. He planted plants of three different colors in it. Ten of them are yellow, and there are 80% more of those in purple. There are only 25% as many green flowers as there are yellow and purple flowers. How many flowers does Mark have in his garden?


Jack earned from the brownies $3 per brownie * 4 brownies = $12. Jack earned from the lemon squares $2 per square * 5 squares = $10. He still needs to earn $50 - $12 - $10 = $28. He sells cookies for $4 each, so Jack still needs to sell $28 / $4 = 7 cookies.
The answer: 7
Reverse engineering the question: Jack is running a bake sale to help pay for his basketball team's uniforms. He's already sold 4 brownies for $3 each and 5 lemon squares for $2 each. If Jack's goal is to make $50 and he sells cookies for $4 each, how many cookies does he need to sell to reach his goal?

A dietitian ate three - fourths of her lunch during her lunch break, containing 3 / 4 * 40 = 30 calories. If the recommended calorie intake by the FDA is 25, the dietitian ate 30 - 25 = 5 more calories than the recommended amount.
The answer: 5
Reverse engineering the question: A dietitian ate three-fourths of her lunch during her lunch break. If the total amount of food she had prepared for lunch had 40 calories, and the recommended calorie intake by the FDA is 25, how many more calories than the recommended amount did she eat?


Reasoning and answer: Mary fed Luna 1 + 1 = 2 cups of kibble. Frank fed Luna 1 - cup plus twice 1 - cup, or 1 + 2 = 3 cups of kibble. In total, they fed Luna 2 + 3 = 5 cups of kibble. Thus, if the new bag held 12 cups of kibble, the next morning, 12 - 5 = 7 cups of kibble remained in the bag.
The answer: 7
