A: If in six years Xavier will be 30 years old, he is 30 - 6 = 24 years old now. If Xavier is twice as old as Yasmin, Yasmin is 24 / 2 = 12 years old. The total of their ages now is 12 + 24 = 36 years. The answer is 36.
Question: Ivar owns a stable. He recently has 3 horses and each horse consumes 5 liters of water for drinking and 2 liters for bathing per day. If he added 5 horses, how many liters of water does Ivar need for all the horses for 28 days?
Answer: The total horse he owns is 5 + 3 = 8. The total liters of water each horse consumes is 5 + 2 = 7. So, the total water all the horses consume every day is 7 x 8 = 56. And the total of liters of water they consume every week is 56 x 7 = 392. Therefore, the total liters of water they consume for the entire month is 392 x 4 = 1568. The answer is 1568.
[Question]Greg and Sarah have 18 apples that they are going to split evenly. Susan has twice as many apples as Greg will end up with. Mark has 5 fewer apples than Susan. Their mom needs 40 apples to make an apple pie. How many will she have left over?
[Answer]Greg and Sarah will split their apples, so 18 apples / 2 = 9 apples per child. Susan has 2 * 9 apples = 18 apples. Mark has 18 apples - 5 apples = 13 apples. Combined the children have 9 apples + 9 apples + 18 apples + 13 apples = 49 apples. Mom will have 49 apples - 40 apples = 9 apples left over. The answer is 9.
[Question]Lucille is wondering who has the tallest house between her and her neighbors. His family's house is 80 feet tall. One neighbor's house is 70 feet tall. Another neighbor's house is 99 feet tall. How much shorter is Lucille's house than the average height?
[Answer]
The houses are 249 feet in total because 70 + 80 + 99 = 249. The average height is 83 feet because 249 / 3 = 83. Her house is 3 feet shorter because 83 - 80 = 3. The answer is 3.
