Question: If you take the fastest speed of a rabbit and double it, add 4 to that then double it again you get 188. How fast is the rabbit?
Answer: You doubled a number to get 188 so in reverse, you would divide by 2 so 188 / 2 = 94. You added 4 to this number and in reverse, you would subtract by 4 so 94 - 4 = 90. You doubled a number to get 90 so in reverse you would divide by 2 so 90 / 2 = 45 is the fastest speed. The answer is 45.
[Question]John visits three different countries. He stays in the first country for 2 weeks and he spends twice as long in each of the other two countries. How much time does he spend on the trip?

Question: The average of marks scored in four tests by Jake was 75. If jake scored 80 marks in the first test and 10 more in the second test, and an equal number of marks in the third and fourth test, calculate the marks he scored in the third test.
Answer: Since the average of marks scored in four tests by Jake was 75, the total marks that he scored in the four tests are 4 * 75 = 300. If jake scored 80 marks in the first test and 10 more in the second test, he scored 80 + 10 = 90 marks in the second test. The combined marks for the first and the second test is 90 + 80 = 170. The total marks Jake scored in the third and fourth test is 300 - 170 = 130. Since Jake scored an equal number of marks in the third and fourth tests, he scored 130 / 2 = 65 marks in each of the third and fourth tests. The answer is 65.
[Question]Five less than three times the number of Doberman puppies plus the difference between the number of Doberman puppies and the number of Schnauzers is equal to 90. If the number of Doberman puppies is 20, how many Schnauzers are there?
[Answer]Three times the number of Doberman puppies is 3 * 20 = 60. Five less than three times the number of Doberman puppies is 60 - 5 = 55. Let's say the number of Schnauzers is s. The difference between the number of Doberman puppies and the number of Schnauzers is s - 20. Five less than three times the number of Doberman puppies plus the difference between the number of Doberman puppies and the number of Schnauzers is equal to 90, meaning 55 + s - 20 = 90. The number of Schnauzers which is s + 55 - 20 = 90. This evaluates to s + 35 = 90. There are s = 55 Schnauzers. The answer is 55.
[Question]Marcus wants to buy a new pair of shoes. He decided to pay not more than $130 for them. He found a pair for $120, on which he got a discount of 30%. How much money will he manage to save by buying these shoes and not spending the assumed maximum amount?
[Answer]
The discount on the shoes Marcus found is 120 * 30 / 100 = $36. That means he only had to pay 120 - 36 = $84. So Marcus was able to save 130 - 84 = $46. The answer is 46.
