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: 90000
Reverse engineering the 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.


Reasoning and answer: First convert the ginger to teaspoons: 3 tablespoons * 3 teaspoons / tablespoon = 9 teaspoons. Then convert the garlic to teaspoons: 2 tablespoons * 3 teaspoons / tablespoon = 6 teaspoons. Then find how much chile powder there is: 1 teaspoon * 4 = 4 teaspoons. Then add up the amount of each spice to find the total amount: 9 teaspoons + 6 teaspoons + 4 teaspoons + 1 teaspoons + 1 teaspoon = 21 teaspoons. Then divide the amount of ginger by the total amount of spice paste and multiply by 100% to find the percentage of the spice paste that's ginger: 9 teaspoons / 21 teaspoons * 100% = 42.857, which rounds down to 43%.
The answer: 43

Question: Martha is grinding a spice paste. She adds 3 tablespoons of ginger, 1 teaspoon of cardamom, 1 teaspoon of mustard, 2 tablespoons of garlic, and four times as much chile powder as mustard. What percentage of the spice paste is ginger, rounded to the nearest integer? (Remember there are three teaspoons per tablespoon.)


If Carla sampled 5 cupcakes from each batch and fed them to her dogs, each batch had 65 - 5 = 60 cupcakes afterwards. Since Carla made 45 batches of cupcakes for her daughter's birthday party, after removing the 5 cupcakes from each batch, Carla's daughter and her friends received 45 * 60 = 2700 cupcakes. The total number of people at the party is 19 friends + 1 daughter = 20. After sharing the cupcakes equally among them, Carla's daughter and her friends each received 2700 / 20 = 135 cupcakes.
The answer: 135
Reverse engineering the question: Baking in batches of 65 cupcakes, Carla made 45 batches of cupcakes for her daughter's birthday party. She then took 5 cupcakes from each batch, and fed them to her dogs. If Carla's daughter had 19 friends and they shared the remaining cupcakes equally among them, including the daughter, calculate the number of cupcakes that each of Carla's daughter's friends ate.


Reasoning and answer: He trains 4 * 2 = 8 hours per day. He trains 7 - 2 = 5 days. So he trains 8 * 5 = 40 hour per week. That means he trains 40 * 52 = $2080.
The answer: 2080

Question: James trains for the Olympics. He trains twice a day for 4 hours each time for all but 2 days per week. How many hours does he train a year?


1000 * 1 / 2 = 500 students were taken on a trip to the nearby beach. So 1000 - 500 = 500 students were not taken to the beach. Thus, 1 / 2 * 500 = 250 students who were not taken to the beach were sent home. Thus, 500 - 250 = 250 students are still in school.
The answer: 250
Reverse engineering the question: A school has 1000 students. Half of the students were taken on a trip to the nearby beach. Half of the remaining students were sent home. How many students are still in the school?
