Reasoning and answer: 1 / 4 of 80 men is 80 / 4 = 20 men. 20 men couldn't finish, so 80 - 20 = 60 men remain. 60 * 2 / 3 = 40 men were dehydrated. 1 / 5 of the dehydrated couldn't finish 40 * 1 / 5 = 8 men. 60 - 8 = 52 men finished the race.
The answer: 52

Question: There are 80 men in a race. 1/4 of the men tripped and were unable to finish. 2/3 of the remaining men were dehydrated and 1/5 of those dehydrated men couldn't finish the race. How many men finished the race?


Two pieces of snickers cost $1.5 x 2 = $3. One pack of M&M's costs $3 so 3 packs cost $3 x 3 = $9. The total amount that she needs to pay is $3 + $9 = $12. Julia gave the cashier $10 x 2 = $20. So, her change is $20 - $12 = $8.
The answer: 8
Reverse engineering the question: In a grocery store, Julia bought 2 pieces of Snickers and 3 packs of M&M's. If each piece of Snickers costs $1.5 and a pack of M&M's has the same cost as 2 Snickers, how much is Julia's change if she gave the cashier 2 $10 bills?


Reasoning and answer: Orlan gave Allan 20 x 1 / 4 = 5 meters of rope. So he had 20 - 5 = 15 meters left. Then he gave 15 x 2 / 3 = 10 meters of the rope to Jack. Therefore, Orlan is left with 15 - 10 = 5 meters of rope.
The answer: 5
What was the question?
Question: Orlan gave one-fourth of his 20-meter rope to Allan. He then gave two-thirds of the remaining to Jack. How many meters of rope is left to Orlan?


If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3 * 40 = 120 books. Rebecca and Mara's total number of books is 120 + 40 = 160 books. If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60 + 160 = 220 books.
The answer: 220
Reverse engineering the question: Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books. If Rebecca received 40 books, how many books did Roselyn have before?


Reasoning and answer: A cake for eight people would require 8 / 4 = 2 times as many eggs as a 4 people cake. If a 4 - person cake requires 2 eggs, then an 8 - person cake requires 2 x 2 = 4 eggs. Tyler needs to buy 4 - 3 = 1 more egg.
The answer: 1
What was the question?
Question: The recipe for a four-person cake requires 2 eggs and 4 cups of milk. Tyler wants to use this recipe to make a cake for eight people. If Tyler has 3 eggs in the fridge, how many more eggs does Tyler need to buy?


Reasoning and answer: First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total. Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store. Now to find what was the beginning amount we take the $68.47 total spent in - store + $11.53 in change = $80 to start.
The answer: 80
