Answer the following question.
Mr. Sergio is a fruit grower producing apples, mangoes and oranges. In a particular season, the total produce of apples was twice the total produce of mangoes, and the total produce of oranges was 200 kg more than that of mangoes. If his farm produced 400 kg of mangoes and he sold the fruits at $50 per kg, calculate the total amount of money he got in that season.
Step-by-step reasoning process: If the total production of mangoes was 400, then orange production was 400 + 200 = 600 kg of oranges. Since apple production was twice the total production of mangoes, Mr. Sergio had 2 * 400 = 800 kg of apples. The total quantity of fruits produced at Mr. Sergio's farm is 800 kg of apples + 600 kg of oranges + 400 kg of mangoes = 1800 kg of fruits. If Mr. Sergio sold the fruits at $50 per kg, his total income from the sales is 1800 * $50 = $90000.
The answer is 90000.

Answer the following question.
Bill is doing weight training before trying out for the boxing team. He gets two 2-gallon jugs and fills them 70% full with sand. If sand has a density of 5 pounds/gallon, how many pounds do Bill's improvised weights weigh?
Step-by-step reasoning process: First find the volume of the sand in one jug: 2 gallons * 70% = 1.4 gallons. Then double this amount since there are two jugs: 1.4 gallons * 2 = 2.8 gallons. Then multiply the total volume by the density of sand to find the total weight: 2.8 gallons * 5 pounds / gallon = 14 pounds.
The answer is 14.

Answer the following question.
Tony drives a car that gets 25 miles to the gallon. He drives 50 miles round trip to work 5 days a week. His tank holds 10 gallons. He begins the week with a full tank and when he runs out he fills up at the local gas station for $2 a gallon. How much money does Tony spend on gas in 4 weeks?
Step-by-step reasoning process: First, we need to determine how many miles Tony drives in 4 weeks. We do this by performing 50 * 5 = 250 miles per week. Next, we multiply the weekly total by 4 by performing 4 * 250 = 1000 miles in 4 weeks. Now, we need to find out how many times Tony needs to fill up his gas tank. His gas tank holds enough gas to last 25 * 10 = 250 miles. This means in 4 weeks, he needs to fill up his tank 1000 / 250 = 4 times. Since Tony's gas tank holds 10 gallons, this means he needs to pay for 4 * 10 - 40 gallons of gas in a month. Since gas costs $2 a gallon, this means Tony spends 40 * 2 = $80 on gas every month,.
The answer is 80.

Answer the following question.
Flora has been experiencing frequent fractures. Dr. Juan has asked her to strengthen her bones by drinking 105 gallons of milk within 3 weeks. Flora thinks that drinking 3 gallons of milk daily will be enough, but her brother says she'll still need to drink more. To fulfill Dr. Juan’s requirement, how many more gallons must Flora drink daily?
Step-by-step reasoning process: 3 weeks translate to 3 * 7 days = 21 days. To meet Dr. Juan’s recommendation would mean drinking 105 / 21 = 5 gallons daily. This means that Flora must drink 5 - 3 = 2 more gallons daily.
The answer is 2.
