Gus eats 2 + 3 = 5 eggs for breakfast and lunch. Including dinner, he eats a total of 5 + 1 = 6 eggs.
The answer: 6
Reverse engineering the question: Gus eats 2 eggs-omelet for breakfast. He has an egg salad sandwich made with 3 eggs for lunch. He then has an egg drop soup made with 1 egg for dinner. How many eggs did Gus eat altogether?
Reasoning and answer: The number of males in the party was 2 males / 3 guests * 60 guests = 40 males. If the total number of people at the party was 60, then there were 60 guests - 40 males = 20 females.
The answer: 20
What was the question?
Question: Princeton had a gender reveal party and invited all of his fellow employees to celebrate with him. If the total number of guests were 60, and 2/3 were male guests, how many female guests attended the party?
First Day:4 inches. Second Day: 5(4) = 20 inches. Third Day: (4 + 20) - 6 = 18 inches.
The answer: 18
Reverse engineering the question: Tropical Storm Sally brings 3 days of rain to southern Texas. The first day it rained 4 inches. The second day it rained 5 times as much as the first day, and the third day it rained 6 inches less than the sum of the first two days. How much did it rain on the third day?
Reasoning and answer: Pulling a loaded sled at 10 mph for 180 miles takes 180 / 10 = 18 hours. Pulling an unloaded sled at 20 mph for 120 miles takes 120 / 20 = 6 hours. Pulling a loaded sled at 10 mph for 80 miles takes 80 / 10 = 8 hours. Pulling an unloaded sled at 20 mph for 140 miles takes 140 / 20 = 7 hours. In total, Toby will have pulled the sled for 18 + 6 + 8 + 7 = 39 hours.
The answer: 39
What was the question?
Question: Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled?
Out of the 20 students, 20 x 1 / 4 = 5 students stayed in the classroom. While 20 - 5 = 15 students went to the playground. Out of these 15 students, 15 x 1 / 3 = 5 are boys. Therefore, 15 - 5 = 10 girl students from this class are in the playground.
The answer: 10
Reverse engineering the question: There are 20 students in a class. Only one-fourth of the students stayed in the classroom while the rest went to the playground. Of those who went to the playground, one-third are boys. How many girls are there on the playground from this class?
Max can deliver a maximum of 35 * 7 = 245 packages in one week. For two days Max has carried the maximum number of packages, which in total means 2 * 35 = 70 packages. One day Max has carried only 1 / 7 of the maximum capacity, that is 1 / 7 * 35 = 5 packages. On two other days, Max delivered only 4 / 5 * 35 = 28 packages. That means, Max could deliver 245 - 28 - 5 - 70 - 50 = 92 more packages.
The answer: 92
Reverse engineering the question:
Max works for a delivery company as a courier. During one working day, he can deliver a maximum of 35 packages. One week, Max delivered the maximum number of packages, only twice. On two other days, Max unloaded a total of 50 packages, and on one day he unloaded only one-seventh of the maximum possible daily performance. On the last two days, the sum of the packages transported was only fourth-fifth of the maximum daily performance. How many more packages could Max deliver during that week, if he would work at maximum performance?
