Question: Kirill is 14 less centimeters in height than his brother. Together their heights equal 112 centimeters. How tall is Kirill in centimeters?
Answer: Let B = brother's height in cm. Kirill = B - 14. 2B - 14 = 112 cm. 2B = 126. B = 63 cm. Kirill = 63 - 14 = 49 cm. Kirill is 49 centimeters tall. The answer is 49.
[Question]An apple tree produced 200 apples in a particular season. The tree made 20% fewer fruits the following season, but the tree fruits production in the second season doubled during the third season. Calculate the total number of fruits the apple tree grew in the three seasons.
[Answer]If the tree produced 200 apples in the first season, there were 20 / 100 * 200 = 40 fewer fruits in the second season. The total production from the apple tree in the second season is 200 - 40 = 160. In the two seasons, the apple tree produced 160 + 200 = 360 fruits. The apple tree doubled the number of fruits it produced in the third season, totaling 160 * 2 = 320. In the three seasons, the apple tree produced 320 + 360 = 680 apples. The answer is 680.

A: The number of chairs at the round tables is 2 tables × 6 chairs / table = 12. The number of chairs at rectangular tables is 2 tables × 7 chairs / table = 14. There are 12 chairs + 14 chairs = 26 chairs in the canteen. The answer is 26.
Question: Nora's mother tells her to go and pick oranges from their farm. She picks 80 oranges from one tree, 60 from another tree, and 120 from the third tree. What's the total number of oranges she picked?
Answer: After picking 80 oranges from the first tree and 60 oranges from the second tree, she has 80 + 60 = 140 oranges. When she adds 120 more oranges from the third tree, she has 140 + 120 = 260 oranges. The answer is 260.
[Question]Milly is figuring out how long she needs to spend studying. She knows that her math homework will take 60 minutes. Her geography homework will take half as long as her math homework, and her science homework will take time equal to the mean amount of time she spent studying math and geography. How many minutes does Milly spend studying?
[Answer]First find how long Milly spends studying geography by dividing her math homework time by 2: 60 minutes / 2 = 30 minutes. Now find the total amount of time Milly spent on math and geography: 30 minutes + 60 minutes = 90 minutes. Now calculate the mean amount of time Milly spends on math and geography by dividing the total time spent by the number of subjects, which is 2: 90 minutes / 2 = 45 minutes. Now add the time Milly spent on all three subjects to find the total: 45 minutes + 30 minutes + 60 minutes = 135 minutes. The answer is 135.
[Question]8 jumbo scallops weigh one pound and cost $24.00 a pound. Nate is pairing 2 scallops with a corn bisque as a light summer dinner. He’s cooking for 8 people. How much will the scallops cost?
[Answer]
He’s cooking for 8 people and wants to serve 2 scallops per person so he needs 8 * 2 = 16 scallops. 8 jumbo scallops come in 1 pound and he needs 16 scallops so he will need 16 / 8 = 2 pounds of scallops. A pound of scallops weigh $24.00 and he needs 2 pounds so it will cost him 24 * 2 = $48.00 for scallops. The answer is 48.
