Gordon has 4 / 2 = 2 Persians. Gordon has 2 + 1 = 3 Maine Coons. Hawkeye has 3 - 1 = 2 Maine Coons. In total, they have 4 + 2 + 2 + 3 + 2 + 0 = 13 cats.
The answer: 13
Reverse engineering the question: Jamie owns 4 Persian cats and 2 Maine Coons. Gordon owns half as many Persians and one more Maine Coon than Jamie. Hawkeye owns one less Maine Coon than Gordon and no Persian cats. If they bring all of their cats together to play, how many cats are there in total?
Reasoning and answer: 60 x 3 / 4 = 45 females are married which means there are also 45 married males. If 1 / 4 of the men are married, which represents 45 men, then 4 * 45 = 180 is the total number of men who attended the party. Thus, there are a total of 60 women and 180 men, or a total of 60 + 180 = 240 people at the party.
The answer: 240
What was the question?
Question: There were 60 women at the party, and three-fourths of these women were married and brought their husbands with them to the party. If 3/4 of the men at the party were single, how many people attended the party?
Let x be the number of shark sightings in Cape May. 26 = 5 + 3x. 21 = 3x. x = 7.
The answer: 7
Reverse engineering the question: Daytona Beach has 26 shark sightings a year. Daytona Beach has 5 more than triple the number of shark sightings as Cape May. How many shark sightings are there in Cape May?
Reasoning and answer: The amoeba will divide into 1 * 2 = 2 amoebae after 2 days. The amoeba will divide into 2 * 2 = 4 amoebae after 4 days. The amoeba will divide into 4 * 2 = 8 amoebae after 6 days. The amoeba will divide into 8 * 2 = 16 amoebae after 8 days.
The answer: 8
What was the question?
Question: An amoeba reproduces by fission, splitting itself into two separate amoebae. An amoeba reproduces every two days. How many days will it take one amoeba to divide into 16 amoebae?
The total amount Evan has is $1 + $12 = $13. So Evan still needs $20 - $13 = $7.
The answer: 7
Reverse engineering the question: David found $12 on the street. He then gave it to his friend Evan who has $1 and needed to buy a watch worth $20. How much does Evan still need?
There are 3 * 20 = 60 green marbles. There are 60 * 20 / 100 = 12 yellow marbles. In total there are 3 * 60 = 180 marbles. That leaves 180 - 20 - 60 - 12 = 88 marbles of another color in the box.
The answer: 88
Reverse engineering the question:
In a big box, there are marbles in 4 colors. Inside, there are 20 red marbles. There are three times more green marbles than red. Yellow marbles make up 20% of the green marbles. How many marbles are of a different color if the total of all marbles in the box is three times more than the number of green marbles?
