Question: If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood before twenty new dogs were born, and now there are twice as many dogs as cats, how many cats were in the neighborhood, to begin with, if there are 20 cats now?
Answer: Step-by-step reasoning process: Now there are twice as many dogs as cats, and if the number of cats is 20, there are 2 * 20 = 40 dogs. Before twenty new ones were born, the number of dogs in the neighborhood originally was 40 - 20 = 20. If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood, there were 20 * 2 = 40 cats in the neighborhood.
So the answer is 40.

Question: Ravi can jump higher than anyone in the class. In fact, he can jump 1.5 times higher than the average jump of the three next highest jumpers. If the three next highest jumpers can jump 23 inches, 27 inches, and 28 inches, how high can Ravi jump?
Answer: Step-by-step reasoning process: The total height the next three highest can jump is 78 inches because 23 + 27 + 28 = 78. The average height they can jump is 26 inches because 78 / 3 = 26. Ravi can jump 39 inches high because 26 x 1.5 = 39.
So the answer is 39.

Question: Hannah is making banana bread. She needs to use 3 cups of flour for every cup of banana mush. It takes 4 bananas to make one cup of mush. If Hannah uses 20 bananas, how many cups of flour should she use?
Answer: Step-by-step reasoning process: First find the number of cups of banana mush Hannah gets: 20 bananas / 4 bananas / cup = 5 cups. Then multiply the number of cups of mush by the ratio of flour to mush to find the number of cups of flour: 5 cups mush * 3 cups flour / 1 cup mush = 15 cups flour.
So the answer is 15.

Question: Marta is arranging floral centerpieces for a reception party. Each arrangement needs to have 8 roses,12 daisies, 3 snapdragons and twice as many lilies. The reception will have 10 tables. How many flowers will she need in total to fill this order?
Answer:
Step-by-step reasoning process: She needs twice as many lilies as the 3 snapdragons in the arrangement so she needs 2 * 3 = 6 lilies. She needs 8 roses, 12 daisies, 3 snapdragons and 6 lilies for a total of 8 + 12 + 3 + 6 = 29 flowers per arrangement. She needs 29 flowers per each of the 10 tables for a total of 29 * 10 = 290 flowers.
So the answer is 290.
