In total, she spent 2 * $20 + 3 * $25 + $150 = $265. Thus her remaining balance is $500 - $265 = $235.
The answer: 235
Reverse engineering the question: Victoria had $500. She went to the market and bought 2 packets of rice each at $20, 3 packets of wheat flour each at $25, and 1 soda at $150. What was her remaining balance?


Reasoning and answer: Initially, Lizzy had $30; she loaned out $15 so she has $30 - $15 = $15 left. Her friend is returning the $15 with 20% interest for a total of $15 + ($15 * (20 / 100)) = $18. Lizzy will now have $15 + $18 = $33.
The answer: 33
What was the question?
Question: Lizzy had $30. She loaned out $15 to her friend. How much will Lizzy have if her friend returned the money with an interest of 20%?


She got 5 gift cards because 50 / 10 = 5. She got 15 thank you cards because 5 / (1 / 3) = 15. She has 50 students because 15 / .3 = 50.
The answer: 50
Reverse engineering the question: Ms. Jones got thank you cards from 30% of her class. 1/3 of these contained a gift card for $10. If she got $50 in gift cards, how many students were in her class?


Reasoning and answer: The first 6 bunches had 6 x 9 x 14 = 756 bananas. There were 10 - 6 = 4 remaining bunches. The 4 remaining bunches had 4 x 12 x 9 = 432 bananas. All together, there were 756 + 432 = 1188 bananas. Each monkey would get 1188 / 12 = 99 bananas.
The answer: 99
What was the question?
Question: A family of 12 monkeys collected 10 piles of bananas. 6 piles had 9 hands, with each hand having 14 bananas, while the remaining piles had 12 hands, with each hand having 9 bananas. How many bananas would each monkey get if they divide the bananas equally amongst themselves?


Dave weighs 175 pounds and can bench press three times his body weight, so he can bench press 175 * 3 = 525 pounds. Craig can only bench press 20% of Dave's 525 pounds, so Craig can bench press .20 * 525 = 105 pounds. Craig bench presses 105 pounds and Mark does 50 pounds less than Craig, so Mark can only press 105 - 50 = 55 pounds.
The answer: 55
Reverse engineering the question: Dave weighs 175 pounds and can bench press three times his body weight. Craig can only bench press 20% of the amount Dave can. Mark is new and can bench press 50 pounds less than Craig. How much can Mark bench press?


The number of ripe mangoes from the tree is 3 / 5 * 400 = 240. If Lindsay eats 60% of the ripe mangoes, she eats 60 / 100 * 240 = 144 mangoes. The total number of ripe mangoes remaining is 240 - 144 = 96.
The answer: 96
Reverse engineering the question:
3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
