Amalia can read 1 page in 2 / 4 = 0.5 minutes. Hence, she can read 18 pages in 18 x 0.5 minutes = 9 minutes.
The answer: 9
Reverse engineering the question: Amalia can read 4 pages of her book in 2 minutes. How many minutes will it take her to read 18 pages of her book?
Reasoning and answer: One cheesecake was 30% cheaper than the apple pie, which means, it was 25 / 100 * 12 = $3 cheaper. So for one cheesecake, Natalie needed to pay 12 - 3 = $9. The six - pack of muffins was two times more expensive than the cheesecake, which means its price was 9 * 2 = $18. So for two cheesecakes, Natalie paid also 9 * 2 = $18. So for all her shopping she paid 18 + 18 + 12 = $48.
The answer: 48

Question: Natalie bought some food for a party she is organizing. She bought two cheesecakes, an apple pie, and a six-pack of muffins. The six-pack of muffins was two times more expensive than the cheesecake, and one cheesecake was only 25% cheaper than the apple pie. If the apple pie cost $12, how much did Natalie pay for all her shopping?
The total number of calories he gets per day is 20 x 3 = 60. Therefore the total number of calories he will get after 2 days is 60 x 2 = 120.
The answer: 120
Reverse engineering the question: Dimitri eats 3 burgers per day. Each burger has a total of 20 calories. How many calories will he get after two days?
Reasoning and answer: In a day, Mr. Jesiah's total income from the sale of the milk is $3.55 / gallon * 200 gallons / day = $710 / day. In June, his total income is $710 / day * 30 days = $21300. The net income from the sale is $21300 - $3000 = $18300.
The answer: 18300
What was the question?
Question: Mr. Jesiah is a dairy cow farmer with cows producing 200 gallons of milk every day. The expenses for maintenance of the dairy farm and purchase of feeds is $3000 per month. Calculate his total income in June if he sells 1 gallon of milk at $3.55.
This year's total production is 5000 * 2 = 10000 phones. A quarter of this year's production is 10000 / 4 = 2500 phones. The number of phones left after selling a quarter of the production is 10000 2500 = 7500 phones.
The answer: 7500
Reverse engineering the question: A phone factory makes twice as many phones as last year. Last year's production was 5000 phones. If a quarter of this year's production is sold, how many phones are left in the factory?
There are 3 families of 4 meaning there are 3 * 4 = 12 people in the vacation rental. They all use 1 oversized beach towel a day so they use 1 * 12 = 12 towels a day. They use 12 towels a day for 7 days so in one week they use 12 * 7 = 84 beach towels. The washing machine can only hold 14 towels and they have 84 towels to wash which means there are 84 / 14 = 6 loads of laundry.
The answer: 6
Reverse engineering the question:
3 families of 4 people shared a vacation rental for 7 days. Everyone uses 1 oversized beach towel a day before getting a new one. The washing machine can hold 14 oversized beach towels per load. How many loads of laundry will it take to wash all the oversized beach towels?
