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? Let's be accurate as possible.
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: 78400.
