When you add up the temperature for the entire week, it comes to 40 + 50 + 65 + 36 + 82 + 72 + 26 = 371. These temperatures were over 7 days so the average temperature was 371 / 7 = 53 degrees.
The answer: 53
Reverse engineering the question: September's temperature fluctuated severely in 1 week. They started off with 40 degrees on Sunday then hit 50 on Monday, 65 on Tuesday, 36 on Wednesday, 82 on Thursday, 72 on Friday and ended the week at 26 on Saturday. What was the average temperature for that week?


Reasoning and answer: Yesterday, Uncle Welly was able to plant 50 + 20 = 70 roses. Today, he planted 2 x 50 = 100 roses. Therefore, Uncle Welly has 50 + 70 + 100 = 220 roses planted on his vacant lot.
The answer: 220
What was the question?
Question: Two days ago, Uncle Welly planted 50 roses on his vacant lot. Yesterday, he planted 20 more roses than the previous day. Today, he planted twice the number of roses than two days ago. How many roses did Uncle Welly plant in his vacant lot?


There were 50 x 3 = 150 tadpoles. There are 50 - 7 = 43 fish left in the pond. There are 150 / 2 = 75 tadpoles left in the pond. There are 75 - 43 = 32 more tadpoles than fish in the pond now.
The answer: 32
Reverse engineering the question: There were 50 fish in a pond and 3 times as many tadpoles. If Curtis catches 7 fish and half the tadpoles develop into frogs, how many more tadpoles than fish are there in the pond now?


Reasoning and answer: All the animals have 4 legs. His 3 dogs will need 3 * 4 = 12 shoes. His 2 cats will need 2 * 4 = 8 shoes. His ferret will need 1 * 4 = 4 shoes. Olly will need 12 + 8 + 4 = 24 shoes.
The answer: 24
What was the question?
Question: Olly wants to get shoes to protect his pets’ paws. He owns 3 dogs, 2 cats, and a ferret. How many shoes does he need?


She needs 2 * 2 = 4 packages of flour for 2 cakes. 4 packages of flour cost 4 * $3 = $12.
The answer: 12
Reverse engineering the question: Claire wants to make 2 cakes for her mother. Two packages of flour are required for making a cake. If 1 package of flour is $3, how much does she pay for the flour that is enough to make 2 cakes?


You first need to know the total weight of the vegetables, so you add each quantity: 15 + 13 + 8 = 36 kg. Then you have to find half of 36: 36 / 2 = 18 kg. So, he sold 18 kg of vegetables.
The answer: 18
Reverse engineering the question:
A fruit and vegetable merchant installed 15 kg of carrots, 13 kg of zucchini and 8 kg of broccoli. He sold only half of them. What mass of vegetables did he sell?
