[Question]: Anthony and his friend Leonel read about the importance of keeping pets at home and decided to start adopting cats and dogs from the local rescue center. Anthony has 12 cats and dogs, 2/3 of which are cats. Leonel has half times as many cats as Anthony and seven more dogs than Anthony. How many animals in total do the two have?
[Answer]: If Anthony has 12 pets, the number of cats is 2 / 3 * 12 pets = 8 cats. The number of dogs that Anthony have is 12 pets - 8 cats = 4 dogs. Leonel has 1 / 2 * 8 cats = 4 cats. If Leonel has seven more dogs than Anthony, then he has 4 dogs + 7 dogs = 11 dogs. The total number of pets the two have is 11 dogs for Leonel + 4 cats for Leonel + 4 dogs for Anthony + 8 cats for Anthony = 27.
So the answer is 27.

[Question]: A small zoo houses a variety of 68 wild animals. After they send a gorilla family of six to a different zoo, they adopt a hippopotamus from another zoo. A while later, an animal rescue contacted them, and the zoo took in three endangered rhinos. Then one of their lionesses gave birth to cubs, and they opened a meerkat exhibit with twice as many meerkats as they had gained lion cubs. The zoo then had 90 animals in all. How many lion cubs were born at the zoo?
[Answer]: Let C be the number of lion cubs. There are 2C meerkats in the new exhibit. The zoo sent 4 gorillas away, so they had 68 - 6 = 62 animals left. They adopted a hippopotamus, so they had 62 + 1 = 63 animals. They took in 3 rhinos, so they had 63 + 3 = 66 animals. Thus, they had 90 - 66 = 24 new lion cubs and meerkats. Therefore, they had C + 2C = 3C = 24 new lion cubs as meerkats. Hence, there were C = 24 / 3 = 8 lion cubs born.
So the answer is 8.

[Question]: As a freelancer, Katherine takes 20 hours to develop a website for her clients. Her junior, Naomi, takes 1/4 times more time to complete creating a similar website. If many clients required her to build their websites in a particular year, and she gave her junior 30 websites to develop, calculate the total number of hours Katherine's junior took to create the 30 websites.
[Answer]:
Katherine's junior takes 1 / 4 * 20 = 5 more hours to build a similar website as Katherine. The total number of hours Katherine's junior takes to build a website is 20 + 5 = 25 hours. If Katherine gave her junior 30 websites to build, her junior spent 30 * 25 = 750 hours on building the 30 websites.
So the answer is 750.
