Kristine traveled on the bus 300 km / 2 = 150 km. With the cab, she had to drive 150 km / 3 = 50 km. In total she had to cover 150 km + 50 km + 300 km = 500 km.
The answer: 500
Reverse engineering the question: Kristine traveled to Paris in France to visit her friend. On the way, she has driven a train for 300 km and a bus for half that distance. After arriving in the city, she had to take a cab and drove three times fewer kilometers than she rode the bus. How many kilometers in total had Kristine traveled to reach her destination?


Reasoning and answer: Four of the five figures are worth 4 * 15 = $60. With one more expensive figure, they are all worth 60 + 20 = $80. On all action figures, Jimmy will lose 5 * 5 = $25 if he sells them cheaper. So if Jimmy sells the figures he will get 80 - 25 = $55.
The answer: 55
What was the question?
Question: Jimmy has a collection of 5 action figures. Each figure is worth $15, except for one which is worth $20. He decided to sell his collection. To do it fast he decided to sell each of them for $5 less than their value. How much will Jimmy earn if he sells all the figures?


Sandra had 2 bags that each contained 6 pieces of candy so 2 * 6 = 12 pieces. Roger had 11 pieces of candy in one bag and 3 pieces in the other so 11 + 3 = 14 pieces. Roger had 14 pieces and Sandra had 12 pieces so Roger has 14 - 12 = 2 more pieces of candy.
The answer: 2
Reverse engineering the question: Sandra had 2 different bags of candy. Each of her bags had 6 pieces of candy left. Her brother, Roger, also had 2 bags of candy. One of his bags of candy had 11 pieces left and the other had 3 pieces left. How much more candy did Roger have?


Reasoning and answer: If Natasha has $60, which is 3 times as much money as Carla, Carla has $60 / 3 = $20. Together, Carla and Natasha have $20 + $60 = $80. Carla has twice as much money as Cosima, meaning Cosima has $20 / 2 = $10. Combined, the three have $10 + $80 = $90. If they buy goods with the amount they have and sell at 7 / 5 of the buying price, the total amount of money they will get from selling the goods is 7 / 5 * 90 = $126. If they earn $126 from the sale of the goods they bought with the money they had, their profit is $126 - $90 = $36.
The answer: 36
What was the question?
Question: Natasha has 3 times as much money as Carla, and Carla has twice as much money as Cosima. If Natasha has $60, and the three decide to buy goods worth the total amount they have and sell the goods at 7/5 of the buying price, how much profit would they make?


Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish.
The answer: 17
Reverse engineering the question: Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.


30 x 5 / 6 = 25 nuts were eaten. Thus, 30 - 25 = 5 nuts were left.
The answer: 5
Reverse engineering the question:
There are 30 different nuts in a bowl. If 5/6 of the nuts were eaten, how many nuts were left?
