Let M be the number of miles Mona biked on Monday. Thus, Mona biked 2M miles on Saturday. In all, Mona biked M + 2M + 12 = 30 miles. Thus, on Monday and Saturday, she biked M + 2M = 3M = 30 - 12 = 18 miles. Therefore, on Monday, Mona biked M = 18 / 3 = 6 miles.
The answer: 6
Reverse engineering the question: Mona bikes 30 miles each week to stay fit. This week, she biked on Monday, Wednesday, and Saturday. On Wednesday, she biked 12 miles. On Saturday, she biked twice as far as on Monday. How many miles did she bike on Monday?


Reasoning and answer: Pauline planted in total 3 * 5 = 15 tomatoes. Pauline also planted 5 * 4 = 20 cucumbers. In total Pauline planted 15 + 20 + 30 = 65 different vegetables. The whole garden can be filled up with 10 * 15 = 150 different vegetables. So Pauline could plant 150 - 65 = 85 more vegetables in her garden.
The answer: 85
What was the question?
Question: Pauline has a garden with vegetables. In it, Pauline has planted 3 kinds of tomatoes - 5 of each kind, 5 kinds of cucumbers - 4 of each kind, and 30 potatoes. In the whole garden, there are 10 rows with 15 spaces in each to plant any vegetable. How many more vegetables could Pauline plant in her garden?


Cersei gave a total of 5 x 2 = 10 cotton candies to her brother and sister. So, the total cotton candies left were 50 - 10 = 40. And she gave 1 / 4 x 40 = 10 cotton candies to her cousin. So, the total number of cotton candies left was 40 - 10 = 30. Therefore, the total number of cotton candies left after she ate 12 of them is 30 - 12 = 18.
The answer: 18
Reverse engineering the question: Cersei bought 50 cotton candies. She gave her brother and sister 5 cotton candies each, then gave the remaining one-fourth of them to her cousin. If she ate 12 cotton candies, how many cotton candies are left?


Reasoning and answer: First, figure out how many gallons of gas Marcus bought by multiply the gas tank's volume by the number of fill - ups: 20 gallons * 2 = 40 gallons. Then multiply that number by Marcus's fuel mileage to find how many miles he drove: 40 gallons * 30 miles / gallon = 1200 miles. Then add that amount to the initial number of miles on Marcus' car to find the final number of miles: 1728 miles + 1200 miles = 2928 miles.
The answer: 2928
What was the question?
Question: Before Marcus went on a road trip to LA, his car had 1728 miles on it. He filled his empty gas tank twice and used up all the gas on the trip. If Marcus's car gets 30 miles per gallon and holds 20 gallons of gas, how many miles does Marcus' car have on it now?


If 10 half - gallons of milk bake 40 cookies, then one half - gallon of milk bakes 40 / 10 = 4 cookies. If one half - gallon of milk bakes 4 cookies. to bake 200 cookies, you'll need 200 / 4 = 50 half - gallons of milk.
The answer: 50
Reverse engineering the question: Juan needs 10 half-gallons of milk to bake 40 cookies with. How many half-gallons of milk does Juan need to bake 200 dozen cookies?


His income tax is 10% of 500 which is 500 * 10% = $50. His tithe costs 10% of $500 which is 500 * 10% = $50. The total expenses are 50 + 55 + 50 = $155. He is then left with $500 - $ 155 = $345.
The answer: 345
Reverse engineering the question:
Alex gets paid $500 a week and 10% of his weekly income is deducted as tax. He also pays his weekly water bill for $55 and gives away another 10% of his weekly income as a tithe. How much money does Alex have left?
