Reasoning and answer: If Luke is 20, he will be 20 + 8 = 28 years old in eight years. In eight years, Mr. Bernard will be 3 times as old as Luke is now, a total of 3 * 20 = 60 years old. Mr. Bernard is now 60 - 8 = 52 years old. The sum of their current ages is 52 + 20 = 72. Their average age is 72 / 2 = 36. 10 less than their average age is 36 - 10 = 26 years.
The answer: 26

Let x represent the age of Jeremy. Amy:(1 / 3)x. Chris:2(1 / 3)x = (2 / 3)x. Total:x + (1 / 3)x + (2 / 3)x = 132. 2x = 132. x = 66 years old.
The answer: 66
Reverse engineering the question: Amy, Jeremy, and Chris have a combined age of 132. Amy is 1/3 the age of Jeremy, and Chris is twice as old as Amy. How old is Jeremy?


Reasoning and answer: During the weekdays, Paris studies 3 hours a day for 5 * 3 = 15 hours. She studies 4 hours on Saturday and 5 hours on Sunday for a total of 4 + 5 = 9 hours on the weekends. If she studies 15 hours during the weekdays and 9 hours on the weekends then she studies 15 + 9 = 24 hours per week. There are 15 weeks in the fall semester and she studies 24 hours a week so she will spend 15 * 24 = 360 hours studying.
The answer: 360

Danai places 12 skulls + 4 broomsticks + 12 spiderwebs + 1 cauldron = 29 decorations. She also puts up twice as many pumpkins around the house as she put spiderwebs, 12 x 2 = 24 pumpkins. Danai will also add 20 + 10 decorations to the 29 + 24 decorations already up = 83 total decorations Danai will put up.
The answer: 83
Reverse engineering the question: Danai is decorating her house for Halloween. She puts 12 plastic skulls all around the house. She has 4 broomsticks, 1 for each side of the front and back doors to the house. She puts up 12 spiderwebs around various areas of the house. Danai puts twice as many pumpkins around the house as she put spiderwebs. She also places a large cauldron on the dining room table. If Danai has the budget left to buy 20 more decorations and has 10 left to put up, how many decorations will she put up in all?


Reasoning and answer: The total time taken for the whole journey is 9:00 - 6:00 = 3 hours. The total time taken in minutes is 3 * 60 = 180 minutes. If it takes 40 minutes to reach the first station, then the rest of the journey takes 180 - 40 = 140 minutes.
The answer: 140

Reasoning and answer: There are 250 / 25 = 10 bundles of potatoes. So, 20 bundles of potatoes amount to $1.9 x 10 = $19. There are 320 / 20 = 16 bundles of carrots. So, 16 bundles of carrots amount to $2 x 16 = $32. Hence, the farmer got $19 + $32 = $51 in all.
The answer: 51
