Question: Alina and her best friend Lucia like to chat a lot. On a particular day, Alina sent 20 fewer messages than her friend Lucia, who sent 120 messages. The next day, Lucia sent 1/3 of the messages she sent the previous day, while Alina doubled the messages she sent on the first day. If they sent the same number of messages on the third day as the first day, what is the total number of messages they sent in those three days?
Answer: On the first day, Alina sent 120 - 20 = 100 messages. The total number for the first day is 100 + 120 = 220 messages. On the second day, Lucia sent 1 / 3 * 120 = 40 messages. Alina sent 100 * 2 = 200 messages on the second day. The total for the second day is 40 + 200 = 240 messages. For the three days, they sent 220 + 220 + 240 = 680 messages. The answer is 680.
[Question]In a dye-making process, a young lady mixes 3/5th of 20 liters of water with 5/6th of 18 liters of vinegar. How many liters of the mixture are obtained?
[Answer]3 / 5th of 20 liters of water is 20 * (3 / 5) = 12 liters. 5 / 6th of 18 liters of vinegar is 18 * (5 / 6) = 15 liters. 12 liters of water mixed with 15 liters of vinegar gives 12 + 15 = 27 - liter mixture. The answer is 27.
Q: The number of short students in a class is 2/5 of the total number of students. If there are 90 tall students, and the class has 400 students, calculate the total number of students with average height.
A: The number of short students in the class is 2 / 5 * 400 = 160. The total number of short and tall students is 160 + 90 = 250. Since there are 400 students in the class, the number of students with average height is 400 - 250 = 150. The answer is 150.
Question: Collin has 25 flowers. Ingrid gives Collin a third of her 33 flowers. If each flower has 4 petals, how many petals does Collin have in total?
Answer: Ingrid gives Collin 33 / 3 = 11 flowers. Now Collin has 25 + 11 = 36 flowers. Since each flower has 4 petals, Collin has a total of 36 * 4 = 144 flowers. The answer is 144.
Q: There are 4 puppies and 3 dogs at a camp. Each dog eats twice as much food as a puppy, but each puppy eats three times as often as a dog. If a dog eats 4 pounds of food three times a day, what would be the total amount of food the dogs and puppies eat in a day?
A:
Eating three times a day, a dog eats 3 * 4 = 12 pounds of food. Since there are 3 dogs at the camp, the total amount of food they eat is 3 * 12 = 36 pounds of food in a day. If each dog eats twice as much food as a puppy, a puppy will eat 4 / 2 = 2 pounds of food in one meal. Each puppy eats three times as often as a dog, and if a dog eats three times in a day, a puppy will eat 3 * 3 = 9 times in a day. Since a puppy eats 2 pounds of food a day, the total amount of food a puppy will eat in a day is 9 * 2 = 18 pounds of food. Four puppies in the camp eat 18 * 4 = 72 pounds of food every day. Together, the dogs and the puppies eat 72 + 36 = 108 pounds of food in a day. The answer is 108.
