Q: Eden's mom is twice as old as Eden, who is twice as old as Devin. If Devin is 12 years old, what's the average age of the three?
A: If Devin is 12 years old, then Eden is 2 * 12 years = 24 years old. Since Eden's mom two times older than Eden, her age is 24 years * 2 = 48 years. In total, they have 48 years + 24 years + 12 years = 84 years. The average age for the three is 84 years / 3 people = 28 years / person. The answer is 28.
Question: Herman likes to feed the birds in December, January and February. He feeds them 1/2 cup in the morning and 1/2 cup in the afternoon. How many cups of food will he need for all three months?
Answer: December has 31 days, January has 31 days and February has 28 days for a total of 31 + 31 + 28 = 90 days. He feeds them 1 / 2 cup in the morning and 1 / 2 cup in the afternoon for a total of 1 / 2 + 1 / 2 = 1 cup per day. If he feeds them 1 cup per day for 90 days then he will need 1 * 90 = 90 cups of birdseed. The answer is 90.
[Question]Candied yams fly off the shelf during the holiday season. The store buys them in bulk boxes of 25 packages. If every third shopper buys a package of candied yams, how many bulk boxes of candied yams will the store need to order for their 375 predicted holiday shoppers?
[Answer]Every third shopper buys a package of candied yams, so the store will need 375 / 3 = 125 packages. At 25 packages per bulk box, the store will need 125 / 25 = 5 bulk boxes of candied yams. The answer is 5.
Q: In a rice field, you can get a total of 20 sacks of rice every harvest. If the yield increases by twenty percent after every harvest, what is the total number of sacks of rice you can get after the first and second harvest?
A: There were 20 x 0.20 = 4 sacks of rice increase after the first harvest. So the total sack of rice that you can get on the next harvest 20 + 4 = 24. Therefore the total number of sacks of rice you will get on the first and second harvest is 20 + 24 = 44. The answer is 44.
Question: Brian can only hold his breath underwater for 10 seconds. He wants to get better, so he starts practicing. After a week, he's doubled the amount of time he can do it. After another week, he's doubled it again from the previous week. The final week, he's increased it by 50% from the previous week. How long can Brian hold his breath for now?
Answer: At the end of his first week, Brian now has doubled his initial time of 10 seconds to 10 * 2 = 20 seconds. At the end of his second week, Brian doubled the previous week's time of 20 seconds to 20 * 2 = 40 seconds. At the end of his third week of practice, Brian adds another 50% of 40 seconds to his time so 40 * .5 = 20 seconds added. Having added 20 seconds to his time from his second week, Brian can now hold his breath for 40 + 20 = 60 seconds. The answer is 60.
