Q: Mr. Reyansh has a dairy farm with 40 cows. Each cow on the farm drinks 80 liters of water daily. He also has a sheep ranch with 10 times the number of cows, with each sheep drinking 1/4 times as much water as a cow does. How many liters of water does Mr. Reyansh use to water all of his animals in a week?
A: If a cow drinks 80 liters of water in a day, it drinks 80 * 7 = 560 liters of water per week. Mr. Reyansh has 40 cows drinking 560 liters of water a week, totaling 560 * 40 = 22400 liters. In the ranch, a sheep drinks 1 / 4 * 80 = 20 liters of water in a day. The total amount of liters a sheep drinks in a week is 20 * 7 = 140 liters. Mr. Reyansh has ten times as many sheep as cows, that is 10 * 40 = 400 sheep. If each sheep drinks 140 liters of water in a week, 400 sheep drinks 400 * 140 = 56000 liters of water. Together, the cows and sheep drink 56000 + 22400 = 78400 liters of water per week. The answer is 78400.

Q: A train travels 360 miles in 3 hours. At the same rate, how many additional hours would it take to travel an additional 240 miles?
A: The rate is 360 / 3 = 120 mph. Then it would take 240 / 120 = 2 additional hours. The answer is 2.

Q: Greg and Katie went to Mrs. Scarlet's gold store to have their gold chests opened. They realized Greg had four times less gold than Katie when Mrs. Scarlet opened the chests. If the total amount of gold is 100, how much gold does Greg have?
A:
Let's say Greg had x number of golds. Katie had 4 * x = 4x. The total number of gold they all had is Katie's 4x + x gold for Gref = 5x. If the total amount of gold, which was 100 = 5x. Then x = 100 / 5 = 20. Greg had x = 20 gold. The answer is 20.
