[Question]To improve her health, Mary decides to drink 1.5 liters of water a day as recommended by her doctor. Mary's glasses hold 250 mL of water. How many glasses of water should Mary drink per day to reach her goal?
[Answer]Each liter of water holds 1000 mL. Mary's goal is to drink 1.5 liters of water a day, which in mL is 1.5 L * 1000 mL / L = 1500 mL. To reach her goal, Mary should drink 1500 mL / 250 mL / glass = 6 glasses of water per day. The answer is 6.
Q: Mr. Sergio is a fruit grower producing apples, mangoes and oranges. In a particular season, the total produce of apples was twice the total produce of mangoes, and the total produce of oranges was 200 kg more than that of mangoes. If his farm produced 400 kg of mangoes and he sold the fruits at $50 per kg, calculate the total amount of money he got in that season.
A: If the total production of mangoes was 400, then orange production was 400 + 200 = 600 kg of oranges. Since apple production was twice the total production of mangoes, Mr. Sergio had 2 * 400 = 800 kg of apples. The total quantity of fruits produced at Mr. Sergio's farm is 800 kg of apples + 600 kg of oranges + 400 kg of mangoes = 1800 kg of fruits. If Mr. Sergio sold the fruits at $50 per kg, his total income from the sales is 1800 * $50 = $90000. The answer is 90000.
Question: Bea's mom planted 50 Mahogany and 30 Narra trees on their farm. Due to a typhoon, a total of 5 trees fell. One more Mahogany tree fell than the number of Narra trees that fell. A month after the typhoon, Bea's mom planted twice as much as the number of the Narra and thrice the number of Mahogany trees that fell. How many trees are now on the farm?
Answer: Before the typhoon, their farm had a total of 50 trees + 30 trees = 80 trees. If there was 1 more than Mahogany than Narra tree that fell, then this means there were 2 Narra trees and 2 + 1 = 3 Mahogany trees that fell during the typhoon. So, Bea's mom planted 2 trees x 2 = 4 Narra trees. She also planted 3 trees x 3 = 9 Mahogany trees. So, her mom planted 4 trees + 9 trees = 13 more trees. After the typhoon, they only had 80 trees - 5 trees = 75 trees left. Therefore, there are 75 trees + 13 trees = 88 trees now. The answer is 88.
[Question]Gwendolyn can read 200 sentences of a book in 1 hour. She just brought a book from the library, having 20 paragraphs per page. What's the total time Gwendolyn will take to read the book if each paragraph has 10 sentences and the book has 50 pages?
[Answer]Gwendolyn just brought a book from the library, having 20 paragraphs per page, and since the book has 50 pages, the number of paragraphs in the book is 50 * 20 = 1000 paragraphs. If each paragraph has 10 sentences, the book's number of sentences is 1000 * 10 = 10000 sentences. Since Gwendolyn can read 200 sentences of a book in 1 hour, she will read 10000 sentences in 10000 / 200 = 50 hours. The answer is 50.
Q: Kyle bikes for 2 hours to work every day. Ten times the time he takes to travel to work and back is the same as the cost of buying a pack of snacks (in dollars). How much will Ryan pay, in dollars, to buy 50 packs of snacks?
A: A round trip to work and back takes 2 * 2 = 4 hours. Ten times the time Kyle takes to travel to work and back is the same as the cost of buying a pack of snacks, meaning the packs are sold at 4 * 10 = $40 each. Ryan will pay $40 * 50 = $2000 to buy 50 packs of snacks?. The answer is 2000.
Question: A small zoo houses a variety of 68 wild animals. After they send a gorilla family of six to a different zoo, they adopt a hippopotamus from another zoo. A while later, an animal rescue contacted them, and the zoo took in three endangered rhinos. Then one of their lionesses gave birth to cubs, and they opened a meerkat exhibit with twice as many meerkats as they had gained lion cubs. The zoo then had 90 animals in all. How many lion cubs were born at the zoo?
Answer:
Let C be the number of lion cubs. There are 2C meerkats in the new exhibit. The zoo sent 4 gorillas away, so they had 68 - 6 = 62 animals left. They adopted a hippopotamus, so they had 62 + 1 = 63 animals. They took in 3 rhinos, so they had 63 + 3 = 66 animals. Thus, they had 90 - 66 = 24 new lion cubs and meerkats. Therefore, they had C + 2C = 3C = 24 new lion cubs as meerkats. Hence, there were C = 24 / 3 = 8 lion cubs born. The answer is 8.
