Reasoning and answer: If Rachel and Leah have the same age, then the sum of their ages would be 34 - 4 = 30. So Leah would be 30 / 2 = 15 years old. Hence, Rachel is 15 + 4 = 19 years old.
The answer: 19

Question: Rachel is 4 years older than Leah. If the sum of their ages is 34, how old is Rachel?


Out of the 40, 40 x 1 / 10 = 4 students are absent. So, 40 - 4 = 36 students are present in school. Out of the 36, 36 x 3 / 4 = 27 students are in the classroom. This means, 36 - 27 = 9 students are in the canteen.
The answer: 9
Reverse engineering the question: There are 40 students in a class. If 1/10 are absent, 3/4 of the students who are present are in the classroom, and the rest are in the canteen, how many students are in the canteen?


Reasoning and answer: If the dog eats two eyes and Oomyapeck eats 22 eyes, then there are a total of 2 + 22 = 24 eyes. With 2 eyes per fish, 24 eyes represent 24 / 2 = 12 fish. If they split that number of fish equally amongst the three of them, then each of them will be given 12 / 3 = 4 fish to eat.
The answer: 4

Question: Ittymangnark and Kingnook are an Eskimo couple living in the most northern region of the Alaskan wilderness. Together, they live with their child, Oomyapeck. Every day Ittymangnark catches enough fish for the three of them to eat for the day and they split the fish equally between the three of them. But after they have split the fish, they give Oomyapeck all of the eyes, who gives two of the eyes to his dog and eats the rest himself. How many fish will each of them be given to eat if Oomyapeck eats 22 eyes in a day?


Mara spent $2 x 2 = $4 for riding the bumper car two times. Riley spent $4 x 4 = $16 for riding the space shuttle 4 times. They spent $5 x 3 = $15 each riding the Ferris wheel 3 times. So, they spent a total of $15 x 2 = $30 riding the Ferris wheel. Therefore the total amount they spent at the carnival is $4 + $16 + $30 = $50.
The answer: 50
Reverse engineering the question: Mara and Riley went to a carnival, Mara rode the bumper car two times, Riley rode the space shuttle four times, and they both rode the Ferris wheel three times. If a ticket for a bumper car cost $2, a ticket for a space shuttle cost $4, and a ticket for a Ferris wheel cost $5, how much money did they spend?


Reasoning and answer: He uses 1 packet per cup of coffee and he has 2 cups a day so that's 1 * 2 = 2 packets. He wants enough to last him 90 days and he uses 2 packets a day so that's 90 * 2 = 180 packets. The packets come 30 to a box and he needs 180 packets so that's 180 / 30 = 6 boxes of sugar substitute. Each box costs $4.00 and he needs 6 boxes so that's 4 * 6 = $24.00.
The answer: 24

Reasoning and answer: A total of 20 x 100 = 2000 grams are sold every week. Since 1 kilogram is equal to 1000 grams, then 2000 / 1000 = 2 kilograms of sugar are sold every week.
The answer: 2
