The answer: 60
What was the question?

2 pounds of steak will cost Ken 2 * 7 = 14 dollars. Subtracting that amount from $20 will give 20 - 14 = 6 dollars. Ken will therefore get 6 dollars back.
The answer: 6
Reverse engineering the question: At Ken's local store, a pound of steak is going for $7. He decides to get two pounds. At the till, he pays using a $20 bill. How much money will he get back?


Reasoning and answer: The total age for the three friends is 40 * 3 = 120. If Molly's age is 30, then Jared and Hakimi have a total age of 120 - 30 = 90. Let's say the age of Hakimi is x. Since Jared is 10 years older than Hakimi, Jared is x + 10 years old. Jared and Hakimi's total age is x + (x + 10) = 90. This translates to 2x = 90 - 10. 2x = 80. Hakimi's age is x = 80 / 2. This gives us x = 40, which is Hamkimi's age.
The answer: 40

Question: The total average age of three friends is 40. Jared is ten years older than Hakimi, and Molly's age is 30. How old is Hakimi?


The shirts weigh 20 / 4 = 5 pounds. The pants weigh 20 / 2 = 10 pounds. So he needs to do 10 + 5 = 15 pounds of laundry. So that would take 15 / 5 = 3 loads of laundry.
The answer: 3
Reverse engineering the question: Jon's laundry machine can do 5 pounds of laundry at a time. 4 shirts weigh 1 pound and 2 pairs of pants weigh 1 pound. If he needs to wash 20 shirts and 20 pants, how many loads of laundry does he have to do?


Reasoning and answer: The total cost of buying bread and ham was $50 + $150 = $200. Together with the cake, Tina paid $200 + $200 = $400 for the items. Since the total percentage for all the items is 100%, the cost of ham and bread is $200 / $400 * 100% = 50% of the total cost of items.
The answer: 50
What was the question?
Question: Tina buys a loaf of bread for $50, 2oz of ham for $150, and a cake for $200. What percent of the cost is the ham and bread?
