Reasoning and answer: First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds.
The answer: 270

Question: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?


He drinks 16 / 4 = 4 of the small bottles each day. That is 4 * 16 = 64 ounces. The larger bottles are 16 * .25 = 4 ounces larger. So the large bottles are 16 + 4 = 20 ounces. So he drinks 20 * 2 = 40 ounces of those a day. So he drinks 64 + 40 = 104 ounces a day. That means he drinks 104 * 7 = 728 ounces a day.
The answer: 728
Reverse engineering the question: Jon drinks a bottle of water that is 16 ounces every 4 hours for the 16 hours he is awake. Twice a day he also drinks a bottle that is 25% larger than those bottles. How much fluid does he drink a week?


Reasoning and answer: Let's say the number of fish that was in the tank before was x. If you caught 4 fewer fish than the number that was there, then you caught x - 4. After adding x - 4 fish into the tank, the tank now had 20 fish, meaning the total number of fish in the tank is x + x - 4 = 20. 2x = 20 + 4. The total number of fish that was initially in the tank is 2x = 24. Initially, there were x = 24 / 2 fish in the tank. x = 12. If you caught 4 fewer fish than the number in my tank initially, you caught 12 - 4 = 8 fish.
The answer: 8

Question: I caught 4 fewer fish than the number in my tank and added them to my fish tank. If the tank has 20 fish right now, how many did I add?


A glass is filled with 6 x 4 / 5 = 24 / 5 ounces of water. So, 10 6 - ounces of glasses contains a total of 24 / 5 x 10 = 48 ounces of water. To fill the 10 glasses to the brim, 10 x 6 = 60 ounces of water are needed. Hence, 60 - 48 = 12 ounces of water are still needed.
The answer: 12
Reverse engineering the question: There are 10 6-ounces of glasses that are only 4/5 full of water. How many ounces of water are needed to fill to the brim all those 10 glasses?


Reasoning and answer: At a germination rate of 60%, 25 seeds will yield 60 / 100 * 25 = 15 plants. At a germination rate of 80%, 25 seeds will yield 80 / 100 * 25 = 20 plants. In total, she will have grown 15 + 20 = 35 plants. If 80% of the plants developed flowers, then she will have grown (80 / 100) * 35 = 28 plants that produce flowers.
The answer: 28

Question: Hortense loves daisies and sunflowers. She planted 25 daisy seeds and 25 sunflower seeds in her flower bed. If 60% of the daisy seeds germinate, and 80% of the sunflower seeds germinate, and 80% of the resulting plants produce flowers, how many plants will she grow that produce flowers?


Reasoning and answer: The garden has space for 6 * 13 = 78 flowers in total. Wilma has two times more green flowers than yellow flowers, which means she has 2 * 12 = 24 green flowers. That leaves us with 78 - 24 - 12 = 42 red flowers in the garden.
The answer: 42
