Riddle: Sheila baked a batch of delicious peanut butter cookies for dessert later in the day. She couldn't eat them while near her husband, though; he was severely allergic to all types of nuts. Plus, the couple's three kids–David, Amanda, and Frank–were all grounded and not allowed to eat sweets for a week. When Sheila went to get the cookies later in the day, she noticed that all of them were gone. She knew it must have been one of her kids who ate the cookies, so she interrogated them. David said that he was helping Dad to bake an apple pie in the kitchen. Amanda said that earlier in the day, she and Dad were eating peanut butter and jelly sandwiches for lunch. She didn't have time for cookies. Frank said that he was doing his homework upstairs. Sheila instantly knew who was lying, and grounded that child for another week. Who was the cookie thief?
Answer: Amanda stole the cookies. She couldn't be eating peanut butter and jelly sandwiches with Dad earlier in the day; after all, Sheila's husband is severely allergic to all types of nuts.
Riddle: Ms. Dell is a math teacher at a high school. She always gives her students summer homework. One year, her students are SO tired of summer homework, and they want her to stop giving it to them. Ms. Dell promises a riddle to the students; whoever gets it right will not get summer homework. The riddle went like this: Add me to myself, and multiply me by four. Divide me by eight, and you will have me once more. What number am I? All of her students gave different answers, but nobody received any summer homework. How is that possible?
Answer: All numbers work with Ms. Dell's riddle! ((x + x) * 4) / 8 will always equal x.
Riddle: Fiona's mother has 12 children. One day, the mother comes home and sees that all 12 children are busy. The first child, January, is reading a book. The second child, February, is cooking dinner. The third child, March, is playing chess. The fourth child, April, is tidying up her room. The fifth child, May, is taking a nap. The sixth child, June, is taking a shower. The seventh child, July, is gardening outside. The eighth child, August, is lighting the fireplace. The ninth child, September, is painting a picture. The 10th child, October, is doing yoga. The 11th child, November, is doing her homework. What is the name of the 12th child, and what is he/she doing?
Answer: The name of the 12th child is Fiona, and she is playing chess with March. Fiona is the name of the 12th child because this is FIONA'S mother. And Fiona is playing chess with March because most of the aforementioned activities require only one person to do, except for playing chess; that activity requires two players.
Riddle: Four friends– Sam, Evan, Rachel, and Olivia– go out for lunch one Saturday morning. The friends order their food, as well as a big pot of blackberry tea. Sam and Rachel decide to drink the tea, but Evan and Olivia do not; Evan takes a large cup of coffee, and Olivia takes lemonade. After drinking the tea, Sam and Rachel feel sick and pass out. When police officers and paramedics arrive, the officers question Evan and Olivia–why did they order different drinks? Evan says, "I took a large cup of coffee because I didn't sleep well last night, and I needed a lot of caffeine to help me stay awake and alert,". Olivia says, "I took lemonade because I am terribly allergic to raspberries. Even one bite gives me a severe rash!". Who poisoned the tea?
Answer: Olivia poisoned the tea. She said she was allergic to raspberries, but the tea the friends ordered contained blackberries, not raspberries. Olivia lied about her allergy to have an alibi.
Riddle: Mrs. Tatum assigned a massive summer assignment to her students–they each had to learn a new language. It could be any language they wanted to learn, though. After the summer break, Mrs. Tatum asked her students what languages they had been learning, and how it had been going. Christopher said, "I enjoy learning Mandarin!". Anthony said, "I've been learning Brazilian; it was really difficult but interesting!". Gianna said, "I chose to learn German because my ancestors are from Germany!". Mrs. Tatum did not believe one of her students. Who is lying?
Answer: Anthony is lying. He couldn't be learning Brazilian because this "language" doesn't exist; people speak Portuguese in Brazil.
Riddle: Jasmine was the worst student in her class. One day, her instructor, Mr. Collins, gave her a chance to stay in her class and not be expelled. He said, "Give me a statement. If the statement is true, you will not be expelled from the class. And if the statement is false, you will be expelled from the class. So, what do you say?". What should Jasmine say to stay in her class?
Answer: Jasmine should say, "I will be expelled from the class,". If we suppose that the statement is true, then Jasmine would not be expelled from the class. But then, it makes the statement false. And if we suppose that the statement is false, then Jasmine would be expelled from the class. But then, it makes the statement true. This phrase creates a paradox, as it cannot be true AND false at the same time.
Riddle: Victoria's best friend, Kayla, meets up with two guys whom Victoria likes: Andrew and Phillip. Both boys ask Kayla who Victoria likes more. Kayla didn't want to reveal her best friend's secret, but she gave the boys a hint: Victoria likes pizza, but she hates burgers. Her favorite color is green, but she doesn't like purple. She has a pet parakeet, but she avoids dogs. And Victoria always goes to the mall instead of the beach. Based on the hint, which boy does Victoria like more?
Answer: Victoria likes Phillip more than Andrew. We have to look for some pattern in the hint Kayla gave the boys. Things such as "mall", "parakeet", "green", and "pizza" contain double letters, whereas things like "beach", "dog", "purple", and "burger" do not. The name "Phillip" contains the double letter "L", but the name "Andrew" doesn't have any double letters. Therefore, Victoria likes Phillip.
Riddle: Ryan and his son Ralph go to a pet store. Ralph sees a very cute rabbit, and asks Ryan to buy it for him. Ryan seems unsure about it, and tells Ralph, "Oh, Ralph, these rabbits can breed every two months, and each time, they will produce four bunnies. We're going to have so many rabbits in our house after a year, and I don't want to take care of them! They'll be too much to take care of!". Ralph laughs at Ryan and says,"Don't be so silly, Dad! We're not going to have that many rabbits in our house after that long!". Who is correct, and how many rabbits will Ralph and Ryan have in a year?
Answer: Ralph is correct; they will only have one rabbit after a year. Ralph and Ryan only saw one rabbit in the pet store, but a single rabbit simply can't breed on its own; it takes TWO rabbits to breed. Therefore, after one year, the two of them will only have that one rabbit…if they choose to buy it, that is.
Riddle: Nicholas loves to collect pairs of shoes. All of his pairs of shoes are blue, except for three; all of them are white, except for three; all of them are brown, except for three; finally, all of them are beige, except for three. How many pairs of shoes does Nicholas have?
Answer: Nicholas has four pairs of shoes. Let's say that x is the number of pairs of shoes Nicholas has. x - 3 should be the term we need to use because the phrase "(color) except for three" means that three pairs of shoes in his collection are NOT of that color. And we should use this term four times because four colors are mentioned in the riddle. 4(x - 3) should be equal to x because once again, x represents the number of pairs of shoes. Here is the algebra: 4 (x - 3) = x 4x - 12 = x -12 = -3x 4 = x Therefore, there are four pairs of shoes in Nicholas' collection: one blue, one white, one brown, and one beige.
Riddle: Lauren has a lemon tree. The number of lemons on the tree doubles every week. In 28 weeks, Lauren should expect the tree to be completely covered with fruit. How many weeks will it take for the tree to be half-covered with apples?
Answer: Zero. If I asked you about lemons, the answer would be 27 weeks because the number of lemons on Lauren's tree doubles every week. However, I asked you about APPLES, and they don't grow on lemon trees; therefore, the answer is zero.
