Ernesto = 11 + 3 = 14. Jayden = 14 / 2 = 7 in 3 years. Now = 7 - 3 = 4. Jayden is 4 years old.
The answer: 4
Reverse engineering the question: In 3 years, Jayden will be half of Ernesto's age. If Ernesto is 11 years old, how many years old is Jayden now?


Reasoning and answer: If there were 26 pink hard hats and Carl took away 4 pink hard hats, the number of pink hard hats that remained is 26 - 4 = 22. John also took away 6 pink hard hats, leaving 22 - 6 = 16 pink hard hats in the truck. If John also took twice as many green hard hats as pink hard hats, he took 2 * 6 = 12 green hard hats. The total number of green hard hats that remained in the truck is 15 - 12 = 3. In the truck, after some are taken, there were 3 green hard hats + 16 pink hard hats = 19 hard hats in the truck. Altogether, 19 green and pink hard hats + 24 yellow hards hats = 43 hard hats remained in the truck.
The answer: 43

Question: In a truck, there are 26 pink hard hats, 15 green hard hats, and 24 yellow hard hats. If Carl takes away 4 pink hard hats, and John takes away 6 pink hard hats and twice as many green hard hats as the number of pink hard hats that he removed, then calculate the total number of hard hats that remained in the truck.


Roger rode for 2 miles in the morning, and then 5 times that in the evening for 5 * 2 = 10 miles ridden in the evening. In total, that means Roger rode 2 + 10 = 12 miles over the course of the day.
The answer: 12
Reverse engineering the question: Roger rode his bike for 2 miles this morning, and then 5 times that amount in the evening. How many miles did Roger ride his bike for?


Reasoning and answer: The almond croissant and the salami and cheese croissant are $4.50 each so that's 2 * 4.50 = $9.00. He buys 2 lattes that are $2.50 each so that's 2 * 2.50 = $5.00. The flavored croissants are $9.00, the lattes are $5.00 and he also grabbed a plain croissant for $3.00 and focaccia for $4.00 for a total of 9 + 5 + 3 + 4 = $21.00.
The answer: 21

Question: Every Sunday, Sean picks up 1 almond croissant and 1 salami and cheese croissant that are $4.50 each. He also grabs a plain croissant for $3.00 and a loaf of focaccia for $4.00. On his way home he stops and picks up 2 lattes for $2.50 each. How much did he spend?


If he had 200 fish and sells 50, he is left with 200 - 50 = 150 fish. If a third of them get spoiled 1 / 3 * 150 = 50 fish get spoiled. The remaining number of fish is now 150 - 50 = 100. He then gets 200 more to make 100 + 200 = 300 fish.
The answer: 300
Reverse engineering the question: Steve owns a lake shop that sells fish. He has a stock of 200 fish. He sells 50 fish and because his refrigerators stop working a third of the remaining fish become spoiled. A new stock of 200 more fish arrives. How many fish does he have in stock now?


Maila read 12 x 2 = 24 pages today. So she was able to read a total of 12 + 24 = 36 pages since yesterday. There are 120 - 36 = 84 pages left to be read. Since she wants to read half of the remaining pages tomorrow, then she should read 84 / 2 = 42 pages.
The answer: 42
Reverse engineering the question:
Julie is reading a 120-page book. Yesterday, she was able to read 12 pages and today, she read twice as many pages as yesterday. If she wants to read half of the remaining pages tomorrow, how many pages should she read?
