Reasoning and answer: In 2005, Simon was 16 + 24 = 40 years old. There are 2010 - 2005 = 5 years between 2005 and 2010. In 2010 Simon would be 40 + 5 = 45 years old.
The answer: 45

Jack scored 3 + 5 = 8 points. Together, Jon and Jack scored 8 + 3 = 11 points. So, Tom scored 11 - 4 = 7 points. Thus, Jon, Jack, and Tom scored a total of 3 + 8 + 7 = 18 points.
The answer: 18
Reverse engineering the question: In a basketball game, Jon scored 3 points. Jack scored 5 points more than Jon, and Tom scored 4 less than the points of Jon and Jack together. How many points did they score altogether?
Reasoning and answer: First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories / carrot * 5 carrots = 100 calories. Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = 250 calories. Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories / cookie = 5 cookies.
The answer: 5

Question: Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get?
Since 40% of his students got below B, 100% - 40% = 60% of Mr. Sanchez's students got B and above. Thus, 60 x 60 / 100 = 36 students got B and above in their final grade.
The answer: 36
Reverse engineering the question: Mr. Sanchez found out that 40% of his Grade 5 students got a final grade below B. How many of his students got a final grade of B and above if he has 60 students in Grade 5?
Reasoning and answer: Wally gives his friends 3 / 4 * 400 = 300 tickets to share. The total ratio that represents the tickets that Jensen and Finley share is 4 + 11 = 15. From the total ratio, the fraction that represents the share that Finley got is 11 / 15, and since he shared with Jensen 300 tickets, he got 11 / 15 * 300 = 220 tickets.
The answer: 220

Question: Wally gives 3/4 of his 400 tickets to his two friends Jensen and Finley, who share the tickets in a ratio of 4:11. How many tickets does Finley get?
Reasoning and answer: After 5 days, Sara has baked 5 days * 10 cakes / day = 50 cakes. After Carol's feast, there are 50 cakes - 12 cakes = 38 cakes remaining. Sara needs 2 cans / cake * 38 cakes = 76 cans of frosting.
The answer: 76

Question:
Every day, Sara bakes 10 cakes and puts them in his refrigerator. He does this for 5 days. Carol then comes over and eats 12 of his cakes. If it takes 2 cans of frosting to frost a single cake, how many cans of frosting does Bob need to frost the remaining cakes?
