The total costs for the fruits is $40 + $50 + $60 = $150. The amount of money given as change is $300 - $150 = $150.
The answer: 150
Reverse engineering the question: Blake goes to the grocery store and spends $40 on oranges, $50 on apples, and $60 on mangoes. If he has $300, how much change was he given?


Reasoning and answer: Kiki spends 60 / 100 * $90 = $54 of her money on hats. The amount she spends on buying scarves is $90 - $54 = $36. If each scarf is sold at $2, Kiki will buy $36 / $2 = 18 scarves.
The answer: 18
What was the question?
Question: Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?


Adam bought 3 sandwiches, so he paid 3 * 3 = $9 for them. In total Adam bought products for 2 + 9 = $11.
The answer: 11
Reverse engineering the question: Adam went to a shop to buy some food for his journey. He bought 3 sandwiches, for $3 each, and a bottle of water for $2. How much did Adam pay for all the shopping?


Reasoning and answer: If Mr. Maximilian has 140 cows and 40% of them have red spots, then 40 / 100 * 140 = 56 cows have red spots. The number of cows with no red spot is 140 - 56 = 84 cows. Out of the 84 cows without a red spot, 25% of them have a blue spot, a total of 25 / 100 * 84 = 21 cows. The number of cows without any spot is 84 - 21 = 63 animals.
The answer: 63
What was the question?
Question: Mr. Maximilian is a dairy animal farmer and has 140 cows on his farm. Forty percent of the cows on his farm have a red spot, 25 percent of the cows without a red spot have a blue spot and the remaining cows do not have any spot. How many cows on the farm have no spot?


The number of yellow chairs is 5 chairs × 4 = 20 chairs. The number of blue chairs is 20 chairs − 2 chairs = 18 chairs. There are 5 chairs + 20 chairs + 18 chairs = 43 chairs in Susan's house.
The answer: 43
Reverse engineering the question: Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house?


He spent an extra 500 - 300 = $200 on the video card. That means the total cost was 1200 + 200 = $1400.
The answer: 1400
Reverse engineering the question:
