[Question]In a week, Rayman works out for half the number of hours Junior takes to work out. Wolverine, their friend, works out for twice the combined total number of hours both Rayman and Junior take during their workouts. Calculate the number of hours Wolverine takes doing her workouts if Rayman does workouts for 10 hours in a week.
[Answer]If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2 * 10 = 20 hours to do his workouts in a week. Altogether, Junior and Rayman take 20 + 10 = 30 hours doing their workouts in a week. Wolverine takes 2 * 30 = 60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes. The answer is 60.
Q: Bella eats 6 apples a day. If during the week she consumes a third of the apples Grace picks, how many apples will Grace have after 6 weeks?
A: Bella eats during the week, 6 apples / day * 7 days / week = 42 apples / week. Grace harvests 42 apples / week * 3 = 126 apples during the week. Leftover after Bella eats, 126 apples / week - 42 apples / week = 84 apples / week. After 6 weeks Grace will have 84 apples / week * 6 weeks = 504 apples. The answer is 504.
Question: I bought a pair of shoes for $51. The shoes were already marked 75% off. What is the original price of the shoes?
Answer: Let X be the original price of the shoes. The discounted price is X - X * 75% = 0.25 * X = $51. The original price of the shirt was X = $51 * 4 = $204. The answer is 204.
[Question]There were 50 racers in a bicycle charity race at the beginning of the race. After 20 minutes, 30 more racers joined the race. The total number of racers doubled after another 30 minutes. If at the end of the race only 130 people finished the race, what's the total number of people who dropped before finishing the race?
[Answer]At the start, there were 50 racers, who were joined by 30 more racers, thus 50 + 30 = 80 racers. After 30 more minutes, the number of racers doubled, totaling 80 * 2 = 160 racers. If the number of racers who finished is 130, the 160 - 130 = 30 racers dropped before finishing. The answer is 30.
Q: James wants to learn to become a chess grandmaster. It takes 2 hours to learn the rules. It then takes him 49 times that long to get a level of proficiency to start playing in local tournaments. After that, he devotes his life to chess and spends 100 times as much as the combined time to get proficient to becoming a master. How much total time did he spend?
A: It takes him 2 * 49 = 98 hours to go from knowing how to play to proficient. So he spends 98 + 2 = 100 hours combined on those. So it takes him 100 * 100 = 10,000 hours to become a master from proficient. So the total time was 100 + 10000 = 10,100 hours. The answer is 10100.
