Question: Lloyd is building a house of cards. He owns 16 decks of cards that have 52 cards each. If each layer of his house of cards has the same exact number of cards, how many cards are there per layer if his house is 32 layers tall?
Answer with step-by-step thinking: He has 832 cards because 16 x 52 = 832. Each layer is 26 cards because 832 / 32 = 26.
So the answer is 26.

Question: During the hot dog eating contest, the 1st competitor ate 12 hot dogs in 3 minutes. The 2nd competitor ate twice that amount and the 3rd competitor ate 25% less than the 2nd competitor. How many hotdogs did the 3rd competitor eat?
Answer with step-by-step thinking: The 2nd competitor ate twice the amount of the 1st competitor's 12 hot dogs So he ate 2 * 12 = 24 hot dogs. The 3rd competitor ate 25% less than the 2nd's 24 hot dogs, which is 24 / 4 = 6 hot dogs. If the 2nd competitor ate 24 hot dogs, and the 3rd ate 25% less than that, then the 3rd competitor ate 24 - 6 = 18 hot dogs.
So the answer is 18.

Question: The difference in the number of pens that Alice and Clara each have matches their age difference. Alice has 60 pens and Clara has 2/5 times as many pens as Alice. If Alice's age is 20 and Clara is older than Alice, calculate Clara's age in 5 years to come.
Answer with step-by-step thinking:
If Alice has 60 pens, Clara 2 / 5 * 60 = 24 pens. The number of pens that Alice has more than Clara is 60 - 24 = 36. Since Alice is 20, and the number of pens that Alice has more than Clara is their age difference, Clara is 20 + 36 = 56 years old. In five years, Clara's age will be 56 + 5 = 61 years.
So the answer is 61.
