First find Jason's grade by subtracting 25 from Jenny's grade: 95 - 25 = 70. Then divide Jason's grade by 2 to find Bob's grade: 70 / 2 = 35.
The answer: 35
Reverse engineering the question: Jenny got a 95 on her paper. Jason's grade was 25 points less than Jenny's, and Bob's grade was equal to half of Jason's grade. What was Bob's grade?


Reasoning and answer: If there are 50 rows of flowers with 400 flowers per row, there are 50 * 400 = 20000 flowers in the garden,. Mr. Wells cuts flowers from 60% of the flowers, which is 60 / 100 * 20000 = 12000 flowers. The total number of flowers remaining in the garden is 20000 - 12000 = 8000.
The answer: 8000
What was the question?
Question: Mr. Wells has a garden of flowers with 50 rows. If each row has 400 flowers and Mr. Wells cuts 60% of the flowers, how many flowers are remaining in the garden?


First find the total cost of the beef: $11 / pound * 3 pounds = $33. Then find the total cost of the fruits and vegetables: $4 / pound * 8 pounds = $32. Then find the total cost of the spices: $6 / jar * 3 jars = $18. Now add the cost of all the items to find Martha's total spending: $33 + $32 + $18 + $37 = $120. Now divide 50 points by $10 to find now many points Martha gets per dollar: 50 points / $10 = 5 points / dollar. Now multiply this exchange rate by Martha's total spending to find how many points she gets before the bonus: $120 * 5 points / dollar = 600 points. Finally, add the 250 point bonus Martha gets for spending more than $100: 600 points + 250 points = 850 points.
The answer: 850
Reverse engineering the question: Martha gets prize points every time she shops at her local grocery store. She gets 50 points per $10 spent, plus a 250 point bonus if she spends more than $100. Martha buys 3 pounds of beef for $11 each, 8 pounds of fruits and vegetables for $4/pound, 3 jars of spices for $6 each, and other groceries totaling $37. How many points does Martha get?


Reasoning and answer: Each cut piece is 20 / 2 = 10 feet long. So they each weigh 10 * 150 = 1500 pounds.
The answer: 1500
What was the question?
Question: John takes a 20-foot log and cuts it in half. If each linear foot of the log weighs 150 pounds how much does each cut piece weigh?


Jean's dress was $10 less than Pauline's $30 dress, meaning it was 30 - 10 = 20 dollars. Ida's dress was $30 more than Jean's $20 dress, meaning it was 30 + 20 = 50 dollars. Patty's dress was $10 more than Ida's $50 dress, meaning it was 50 + 10 = 60 dollars. Therefore, all four women together spent 60 + 50 + 20 + 30 = 160 dollars.
The answer: 160
Reverse engineering the question: If Patty's dress was $10 more than Ida's dress, and Ida's dress was $30 more than Jean's dress, and Jean's dress was $10 less than Pauline's dress, and lastly Pauline's dress was $30, how much did all the ladies spend on dressed put together?


He had 80 - 20 = 60 after the donation. He kept 60 / 2 = 30 after giving half to his brother. So he has 30 * 3 = 90 coins. He then does 1 more donation and has 90 - 10 = 80 coins left.
The answer: 80
Reverse engineering the question:
Jake amasses a fortune of 80 bitcoin. He donates 20 bitcoins to charity. He then gives half of all the bitcoins to his brother. After that, he triples the number of bitcoins he has. Then he donates another 10 coins. How many coins does he have?
