Question: In four years, Annika will be three times as old as Hans. If Hans is now 8 years old, how old is Annika now?
Answer: In four years, Hans will be 8 + 4 = 12 years old. Then Annika will be 12 * 3 = 36 years old. So Annika right now is 36 - 4 = 32 years old. The answer is 32.
[Question]Paddy's Confidential has 600 cans of stew required to feed 40 people. How many cans would be needed to feed 30% fewer people?
[Answer]If there are 40 people, each person gets 600 / 40 = 15 cans. Thirty percent of the total number of people present is 30 / 100 * 40 = 12. If there are 30% fewer people, the number of people who are to be fed is 40 - 12 = 28. Since each person is given 15 cans, twenty - eight people will need 15 * 28 = 420 cans. The answer is 420.
Q: Hannah fills her kids' stockings with 4 candy canes, 2 beanie babies and 1 book. If she has 3 kids, how many stocking stuffers does she buy total?
A: First find the total number of stocking stuffers one kid gets: 4 candy canes + 2 beanie babies + 1 book = 7 stocking stuffers. Then multiply the number of stocking stuffers per kid by the number of kids to find the total number: 7 stocking stuffers / kid * 3 kids = 21 stocking stuffers. The answer is 21.
Question: A farmer planted 30 rows of tomatoes with 10 plants in each row. Each tomato plant yields 20 pieces of tomatoes. How many pieces of tomatoes can the farmer get from all his planted tomatoes?

[Question]Mark goes into the store to buy some groceries. He buys 6 2$ cans of soup, 2 $5 loaves of bread, 2 3$ boxes of cereal, and 2 $4 gallons of milk. When he gets to the register, he opens his wallet to pay and realizes he only has $10 bills in there. How many $10 bills does he need to use to pay?
[Answer]Mark buys 6 $2 cans of soup, meaning he spends 6 * 2 = 12 dollars on soup. Mark buys 2 $5 loaves of bread, meaning he spends 2 * 5 = 10 dollars on bread. Mark buys 2 $3 boxes of cereal, meaning he spends 2 * 3 = 6 dollars on cereal. Mark buys 2 $4 gallons of milk, meaning he spends 2 * 4 = 8 dollars on milk. All added together, this means Mark spends 12 + 10 + 6 + 8 = 36 dollars. Since Mark only has $10 bills, he spends 36 / 10 = 3.6 tens on it, which rounds up to 4 as you cannot spend .6 of an undividable item. The answer is 4.
[Question]Adam has 50 balls. 20 balls are red, 10 are blue, and the rest are either pink or orange. If there are 3 times as many pink as orange balls, how many orange balls are there?
[Answer]
Adam has a total of 50 balls - 20 red - 10 blue = 20 pink and orange balls combined. If we let x be the total number of orange balls, we know that 3x is the number of pink balls. Therefore, 20 balls = x + 3x = 4x. The number of orange balls, x, is 20 balls / 4 = 5 balls. The answer is 5.
