Before going to bed, Rachel did a total of 5 × 12 = 60 problems. In total Rachel did 60 + 16 = 76 maths problems.
The answer: 76
Reverse engineering the question: Rachel solved 5 math problems each minute for 12 minutes before bed, but she didn't finish all of them. The next day, she finished the last 16 problems at lunch. How many math problems did she do in all?


Reasoning and answer: If Legacy has 5 bars, Aleena has 5 bars - 2 bars = 3 bars. In total, they have 5 bars + 3 bars = 8 bars,. Since one bar of gold is worth $2200, the 8 bars they have together are worth 8 bars * $2200 / bar = $17600.
The answer: 17600
What was the question?
Question: Legacy has 5 bars of gold she received from her father. Her friend Aleena has 2 bars fewer than she has. If a bar of gold is worth $2200, calculate the total value of gold the three have together.


2 pigs fed for 7 days is a total of 7 * 2 = 14 feedings. At 10 pounds per feeding, this amounts to a total of 10 * 14 = 140 pounds of pig feed per week.
The answer: 140
Reverse engineering the question: Randy feeds his pigs 10 pounds of feed per pig per day. If Randy has 2 pigs, how many pounds of pig feed will Randy's pigs be fed per week?


Reasoning and answer: First convert the quarantine wait time to hours by multiplying the number of days by the number of hours in a day: 14 days * 24 hours / day = 336 hours. Then add the time Jack spent waiting in customs to the quarantine time: 336 hours + 20 hours = 356 hours.
The answer: 356
What was the question?
Question: When Jack traveled to Canada, he had to wait 20 hours to get through customs, plus 14 days in coronavirus quarantine. How many hours total did Jack have to wait?


Tommy ordered 3 + 3 + 1 = 7 kilograms of apples, oranges and grapes altogether. Therefore, Tommy ordered 10 - 7 = 3 kilograms of strawberries.
The answer: 3
Reverse engineering the question: Tommy ordered a total weight of 10 kilograms of apple, orange, grape, and strawberry fruits. He ordered 3 kilograms of apples, 1 kilogram of orange, and 3 kilograms of grapes. How many kilograms of strawberries did he order?


She will keep 1000000 / 2 = 500000 Safe Moon tokens for herself. For the remaining siblings, they will each receive 500000 / 4 = 125000 tokens. This means that Sandy will have 500000 - 125000 = 375000 tokens more than any of her siblings.
The answer: 375000
Reverse engineering the question:
Sandy bought 1 million Safe Moon tokens. She has 4 siblings. She wants to keep half of them to herself and divide the remaining tokens among her siblings. After splitting it up, how many more tokens will she have than any of her siblings?
