Marlon gave Emily 42 x 2 / 3 = 28 lollipops. So, he only had 42 - 28 = 14 lollipops left. After keeping 4, Marlon gave 14 - 4 = 10 lollipops to Lou.
The answer: 10
Reverse engineering the question: Marlon had 42 lollipops in the beginning. On his way home, he saw Emily and gave her 2/3 of his lollipops. Then, Marlon kept 4 lollipops and gave the rest to Lou. How many lollipops did Lou receive?


Reasoning and answer: If Lizette's average on the 3 quizzes is 94, then the sum of her scores in the 3 quizzes is 94 x 3 = 282. This means that the sum of her scores in the first 2 quizzes is 282 - 92 = 190. Thus, her average for the first 2 quizzes is 190 / 2 = 95.
The answer: 95
What was the question?
Question: Lizette scored 92 on her third quiz giving her an average of 94. What is Lizette's average in her first two quizzes?


Omar drinks 1 / 4 * 12 = 12 / 4 = 3 ounces on the way to work. Omar drinks 1 / 2 * 12 = 12 / 2 = 6 ounces when he gets to his office. When he drinks 1 ounce more, he will have drunk 3 + 6 + 1 = 10 ounces. Thus, there will be 12 - 10 = 2 ounces left in the cup afterward.
The answer: 2
Reverse engineering the question: Omar buys a 12-ounce cup of coffee every morning on the way to work. On the way to work, he drinks one-quarter of the cup. When he gets to his office, he drinks another half of the cup. He forgets to drink any more of his coffee once he starts working, and when he remembers his coffee, he only drinks 1 ounce of the remaining amount because it is cold. How many ounces will be left in the cup afterward?


Reasoning and answer: Jesse bought a novel for $7. She then bought lunch for twice the value of the novel, so lunch cost her $7 x 2 = $14. To find out how much money she has left from her gift she must know the total amount she spent $7 + $14 = $21. Her gift was $50, so she was left with $50 - $21 = $29.
The answer: 29
What was the question?
Question: Jesse received $50 as a gift to buy what she wants. She goes to the mall and falls in love with a novel that costs her $7. Then she went to lunch because she was very hungry and spent twice as much as the novel cost her. How much money did Jesse have left after going to the mall?


The flower shop sold 45 + 20 = 65 daisies on the second day. Twice the number of flowers on the second day is 65 x 2 = 130. So, the flower shop sold 130 - 10 = 120 daisies on the third day. The total daisies sold for 3 days was 45 + 65 + 120 = 230. Therefore, 350 - 230 = 120 daisies were sold on the 4th day.
The answer: 120
Reverse engineering the question: Daisy's Flower Shop sold 45 daisies on its first day. On their second day, they sold 20 more flowers than they did on their first day. On the third day, they sold 10 less than twice the flowers that were sold than on the second day. If the flower shop sold a total of 350 daisies for 4 days, how many daisies were sold on the 4th day?


The perimeter of a square is found by 4 * side, which means the square paper has a perimeter of 4 * 20 = 80. Since the perimeter of the square is 20 cm shorter than the height of the computer screen, the height of the computer screen is 20 + 80 = 100cm.
The answer: 100
Reverse engineering the question:
The perimeter of a square-shaped piece of paper is 20 cm shorter than the height of a computer screen. How many cm is the height of the screen if the side of the square paper is 20 cm?
