Q: Bill composes 20 total math questions for money. Ryan composes twice as many problems as Bill, and Frank composes 3 times as many as Ryan. Assuming each person has to compose 4 different types of math problems in equal proportion out of the total amount, how many problems of each type does Frank compose?
A: Since Ryan composes twice as many problems as Bill's total of 20, this means Ryan composes 20 * 2 = 40 problems. Frank composes 3 times as many as Ryan does, so this means Frank composes 40 * 3 = 120 problems. Since Frank needs to submit 4 types of problems in equal proportion out of his total, this means he needs to make 120 / 4 = 30 problems of each type. The answer is 30.
Question: Ofelia joined a saving challenge wherein she has to save twice the amount she saved from the previous month. In January, she saved $10. How much is she going to save in May?
Answer: Ofelia saves $10 x 2 = $20 in February. She will save $20x 2 = $40 in March. She will save $40 x 2 = $80 in April. Thus, she will save $80 x 2 = $160 in May. The answer is 160.
[Question]Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost?
[Answer]The two sets of plates amount to $20 x 2 = $40. So the table and the two sets of plates amount to $50 + $40 = $90 in all. Since Jude received a $4 change, then he paid a total of $130 - $4 = $126 for the chairs, tables, and plates. Thus, the three chairs cost $126 - $90 = $36. Therefore, each chair cost $36 / 3 = $12. The answer is 12.
Q: John sends his son to prep school. It cost $20,000 per semester. There are 2 semesters in the year. How much does it cost to send the kid to 13 years of school?
A: It cost 20000 * 2 = $40,000 a year. So it cost 40,000 * 13 = $520,000. The answer is 520000.
Question: Markus is twice the age of his son, and Markus's son is twice the age of Markus's grandson. If the sum of the ages of Markus, his son, and his grandson is 140 years, then how many years old is Markus's grandson?
Answer: Let "x" be the age of Markus's grandson. If Markus's son is twice the age of Markus's grandson, then Markus's son is 2 * x. If Markus is twice the age of his son, then Markus is 2 * 2 * x. Therefore, if the sum of the ages of Markus, his son, and his grandson is 140 years, then x + (2 * x) + (2 * 2 * x) = 140 years. Simplifying the equation, we see that 7 * x = 140 years. Therefore, the age of Markus's grandson is x = 20 years old. The answer is 20.
Q: Yuko likes to play board games. He decides to play a game with his brother Yuri. They must roll 3 dice at the same time and move the squares corresponding to the value of the 3 dice. Yuri started and his dice had the following combination: 2, 4, and 5. On Yuko's turn, he rolled 1, 5, and X. How many squares must Yuko's last die move him so that he is in front of his brother?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The sum of Yuri's dice gave, 2 + 4 + 5 = 11 squares. For Yuko to get the same sum in the dice, 1 + 5 + X = 11 squares. Solving the equation, X = 11 - 6, X = 5 squares. To stand in front of his brother, Yuko needs to be at least 1 place in front, so his last die will move him, 5 + 1 = 6 squares. The answer is 6.
