Question: 7 out of 40 people in a cafeteria are wearing checkered shirts. The rest of the people are wearing vertical stripes and horizontal stripes. The number of people wearing horizontal stripes is 4 times as many as the people wearing checkered shirts. How many people are wearing vertical stripes?
Answer: 40 people - 7 people = 33 people are wearing stripes. The number of people wearing horizontal stripes is 4 horizontal stripes / checkered shirt x 7 checkered shirts = 28 horizontal stripes. The number of people wearing vertical stripes is 33 total stripes - 28 horizontal stripes = 5 vertical stripes. The answer is 5.
[Question]Mary bought a packet of 1500 stickers. She shared them between Susan, Andrew and Sam in the ratio 1:1:3 respectively. If Sam gave Andrew two-thirds of his own share, how many stickers does Andrew now have?
[Answer]The sum of the ratio is 1 + 1 + 3 = 5, therefore each part is 1500 / 5 = 300 stickers. Sam got 3 parts for a total of 3 * 300 = 900 stickers. He gave two - thirds of this which is 900 * (2 / 3) = 600 stickers to Andrew. Andrew had one part already, which is 1 * 300 = 300. Andrew now has a total of 300 + 600 = 900 stickers. The answer is 900.
Q: A TV show has been going on for 14 years. Out of those 14 years, 8 seasons had 15 episodes, 4 seasons had 20 episodes, and 2 seasons had 12 episodes. What is the average number of episodes per year?
A: 8 seasons with 15 episodes had 8 x 15 = 120 episodes. 4 seasons with 20 episodes had 4 x 20 = 80 episodes. 2 seasons with 12 episodes had 2 x 12 = 24 episodes. All together, there have been 120 + 80 + 24 = 224 episodes. The average number of episodes a year is 224 / 14 = 16 episodes. The answer is 16.
Question: Marta was about to start the school year and needed to buy the necessary textbooks. She managed to buy five on sale, for $10 each. She had to order two textbooks online, which cost her a total of $40, and three she bought directly from the bookstore for a total of three times the cost of the online ordered books. How much in total did Martha spend on textbooks?
Answer: Marta bought five textbooks on sale, for a total of 5 * 10 = $50. Three textbooks from the bookstore had a cost of 3 * 40 = $120. That means that Marta spent in total 50 + 40 + 120 = $210 on textbooks. The answer is 210.
[Question]Danny has a huge fish tank that contains 94 guppies, 76 angelfish, 89 tiger sharks, and 58 Oscar fish. If he sells 30 guppies, 48 angelfish, 17 tiger sharks, and 24 Oscar fish. How many fish will remain?
[Answer]There were 94 + 76 + 89 + 58 = 317 fishes in the tank. The fish to be sold is 30 + 48 + 17 + 24 = 119. Therefore, Danny will be left with 317 - 119 = 198 fishes. The answer is 198.
