Q: Stella and Twinkle are filling up a truck with a capacity of 6000 stone blocks at the rate of 250 blocks per hour per person. They work for four hours and are then joined by 6 other people who also work at the same rate. How many hours did filling the truck take?
A: Stella and Twinkle filled up the truck at the rate of 250 blocks per hour per person, a total of 2 * 250 = 500 blocks per hour for both. After working for four hours, Stella and Twinkle had filled 4 * 500 = 2000 blocks into the truck. The number of blocks they had to put into the truck for it to be full is 6000 - 2000 = 4000. When 6 more people joined Stella and Twinkle, a total of 2 + 6 = 8 people were filling the truck now. Working at the rate of 250 blocks per person, the eight people filled the truck with 250 * 8 = 2000 blocks in one hour. If there were 4000 blocks that still needed to be put into the truck, the 8 people took 4000 / 2000 = 2 hours to fill the truck with the blocks. The total time it took to fill up the tank is 4 + 2 = 6 hours. The answer is 6.
Question: George and Amelia are picking oranges and apples at an orchard. George picks 45 oranges and 5 more apples than Amelia. Amelia picks 18 fewer oranges than George and 15 apples. How many fruits do they pick altogether?
Answer: Amelia picks 45 - 18 = 27 oranges. The total number of oranges that they pick is 45 + 27 = 72. George picks 15 + 5 = 20 apples. The total number of apples that they pick is 20 + 15 = 35. So, they pick 72 + 35 = 107 fruits altogether. The answer is 107.
[Question]Andy started out the year weighing 156 pounds. He then grew 3 inches and gained 36 pounds. Andy wasn't happy with his weight and decided to exercise. Over the next 3 months, he lost an eighth of his weight every month. How much less does Andy weigh now than at the beginning of the year?
[Answer]Andy weighed 156 + 36 = 192 pounds after growing taller. An eighth of his weight is 1 / 8 x 192 = 24 pounds. Over the next 3 months, Andy lost 24 x 3 = 72 pounds. He now weighs 192 - 72 = 120 pounds. Andy weighs 156 - 120 = 36 pounds less than at the beginning of the year. The answer is 36.
Q: A small poultry farm has 300 chickens, 200 turkeys and 80 guinea fowls. A strange, incurable disease hit the farm and every day the farmer lost 20 chickens, 8 turkeys and 5 guinea fowls. After a week, how many birds will be left in the poultry?
A: There are 300 + 200 + 80 = 580 birds in total. Every day 20 + 8 + 5 = 33 birds are lost. After a week which is 7 days, 33 * 7 = 231 birds would be lost. There would be 580 - 231 = 349 birds left in the poultry. The answer is 349.
Question: Out of the 200 cookies that Javier baked from the recipe he learned online, his wife took 30%, and his daughter took 40 from the remaining cookies. If he ate half of the remaining cookies, how many cookies did they not eat?
Answer: From the 200 cookies, Javier's wife ate 30 / 100 * 200 = 60. After the wife ate 60 cookies, the number of cookies that remained was 200 - 60 = 140. The daughter also ate 40 cookies leaving 140 - 40 = 100 cookies. If Javier ate half of the remaining cookies, he ate 1 / 2 * 100 = 50. The number of cookies that remained is 100 - 50 = 50. The answer is 50.
