Q: Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
A: Her first drink consumed 1 / 4 * 4 = 1 liter of water. Thus there were 4 - 1 = 3 liters of water left in the bottle. Next, she drank 2 / 3 * 3 = 2 liters. Thus, there were 3 - 2 = 1 liters remaining. The answer is 1.
Question: Lavinia's daughter is 10 years younger than Katie's daughter. Lavinia's son is 2 times the age of Katie's daughter. If Katie's daughter is 12 years old, how many years older is Lavinia's son than Lavinia's daughter?
Answer: Lavinia's daughter is 12 - 10 = 2 years old. Lavinia's son is 12 * 2 = 24 years old. Lavinia's son is 24 - 2 = 22 years older than Lavinia's daughter. The answer is 22.
[Question]In a national park, the number of redwoods is 20% more than the number of pines. If there are 600 pines in the national park, calculate the total number of pines and redwoods that are there.
[Answer]If there are 600 pines, there are 20 / 100 * 600 = 120 more redwoods than pine trees in the national park. In total, there are 120 + 600 = 720 redwoods in the national park. Altogether, there are 720 + 600 = 1320 pines and redwoods in the national park. The answer is 1320.
Q: Troy had 300 straws. He fed 3/5 of the straws to the adult pigs and an equal number of straws to the piglets. If there were 20 piglets, how many straws did each piglet eat?
A: The adult pigs ate 3 / 5 * 300 = 180 straws. The total number of straws that the piglets shared is 300 - 180 = 120. Since there were 20 piglets, each piglet ate 120 / 20 = 6 straws. The answer is 6.
Question: John puts $25 in his piggy bank every month for 2 years to save up for a vacation. He had to spend $400 from his piggy bank savings last week to repair his car. How many dollars are left in his piggy bank?
Answer: He saved money for 2 years, which is equal to 12 x 2 = 24 months. The amount of money he saved is $25 * 24 = $600. But he spent some money so there is $600 - $400 = 200 left. The answer is 200.
Q: Richard can clean his room in 22 minutes. Cory takes 3 minutes more than Richard to clean her room while Blake can clean his room 4 minutes more quickly than Cory. If they have to clean their rooms twice a week, how many minutes do all three spend cleaning their rooms each week?
A:
Cory takes 22 + 3 = 25 minutes to clean her room. Blake takes 25 - 4 = 21 minutes to clean his room. The three of them can clean their room in 22 + 25 + 21 = 68 minutes in all. In a week, they spend 68 x 2 = 136 minutes cleaning their rooms. The answer is 136.
