Sarith would run around the adult football field, 12 laps / 3 = 4 laps. So on the children's football field, she managed to run, 4 laps * 2 = 8 laps.
The answer: 8
Reverse engineering the question: Kristin can run three times faster than Sarith. If Kristin runs 12 times around the adult football field and Sarith runs at the same time around the children's football field that is half the distance as the other field, how many laps did Sarith go around the children's football field?


Reasoning and answer: If the price of a shirt in the store was $60, its price was reduced by 20 / 100 * $60 = $12. The price of a shirt was reduced to $60 - $12 = $48. Teagan will pay $48 * 5 = $240 for buying 5 shirts. If the initial price of the leather jacket was $90, the price reduced by 20 / 100 * $90 = $18. The final leather jacket after Mrs. Brynlee reduced the price by 20% is $90 - $18 = $72. Teagan will pay $72 * 10 = $720 for buying 10 leather jackets. The amount of money Teagan paid to Mrs. Brynlee for the shirts and the leather jackets is $720 + $240 = $960.
The answer: 960
What was the question?
Question: Mrs. Brynlee reduced the prices of items in her store by 20% after the local government gave small businesses in her county a subsidy. If the price of a shirt in the store was $60 and that of the leather jacket was $90, calculate the amount of money Teagan will pay for buying 5 shirts and 10 leather jackets at the reduced prices.


7 notebooks cost 7 notebooks x $4 / notebook = $28. 2 books cost 2 books x $7 / book = $14. In total Joe has spent $28 + $14 = $42. He has $56 - $42 = $14 left.
The answer: 14
Reverse engineering the question: Joe’s mother gave him $56 to go to the store. Joe bought 7 notebooks and 2 books. Each notebook costs $4 and each book costs $7. How much money does Joe have left?


Reasoning and answer: Since Kyle can lift 60 more pounds and that is 3 times what he could do before, that means that last year Kyle could lift 60 pounds / 3 = 20 pounds. Kyle can now lift 60 pounds + 20 pounds he could lift last year = 80 pounds.
The answer: 80
What was the question?
Question: Kyle can lift 60 more pounds this year, which is 3 times as much as he could lift last year. How many pounds can Kyle lift in all?


For 4 days, Ivy consumes 2.5 x 4 = 10 liters of water. So Ivy should buy 10 / 2 = 5 bottles of 2 - liter water.
The answer: 5
Reverse engineering the question: Ivy drinks 2.5 liters of water each day. How many bottles of 2-liter water should Ivy buy for her 4 days consumption?


First find the total volume of the smoothie mix: 500 ml + 100 ml = 600 ml. Then divide the total volume by the volume per serving to find the number of servings: 600 ml / 150 ml / serving = 4 servings.
The answer: 4
Reverse engineering the question:
Carla is making smoothies. If she uses 500 ml of watermelon puree and 100 ml of cream, how many 150 ml servings can she make?
