Reasoning and answer: Each basket contains an average of 25 fruits so the 5 baskets in all contain 25 * 5 = 125 fruits. The number of apples, mangoes, peaches and pears is 15 + 30 + 20 + 25 = 90. The remaining fruits are bananas and they are 125 - 90 = 35 in number.
The answer: 35

A pair of rabbits join each cat so there must be 4 cats * 2 rabbits / cat = 8 rabbits. As 3 hares join each rabbit, there must be 8 rabbits * 3 hares / rabbit = 24 hares. Counting all the animals shows there are 1 dog + 4 cats + 8 rabbits + 24 hares = 37 animals running through the field.
The answer: 37
Reverse engineering the question: A dog runs through a field and is joined by a group of 4 cats. 2 rabbits join each cat and 3 hares join each rabbit. How many animals are running through the field?


Reasoning and answer: Each batch serves 6 people, and there are 42 people coming to the party, so she needs to make 42 / 6 = 7 batches. Each batch requires 4 avocados, so she will need 4 * 7 = 28 avocados.

Ellis and her family of 4 will be traveling for 8 hours going and 8 hours coming home = 16 hours total. Each person needs 1 / 2 a bottle of water each hour, so 1 / 2 a bottle x 16 hours = 8 bottles. There are 4 people traveling so 8 total water bottles for each person x 4 people = 32 total water bottles.
The answer: 32
Reverse engineering the question: Ellis is going to take a road trip with her family. First, she needs to figure out how many bottles of water she should bring for everyone. There will be four people total: Ellis, her mother, her sister, and her aunt. They will be on the road to their destination for 8 hours and drive 8 hours to return home. Every hour each person will want to drink 1/2 a bottle of water. How many water bottles will Ellis' family need total?


Reasoning and answer: If Emilio presents 11 gifts and Jorge 6 gifts, together they have presented 11 + 6 = 17 gifts. If Pedro also gives Rosalinda 4 gifts, Rosalinda's total number is 17 + 4 = 21 gifts.
The answer: 21

Reasoning and answer: The park is 2,000,000 square feet because 1000 * 2000 = 2,000,000. Thus, there are 100,000 trees in the park because 2,000,000 / 20 = 100,000.
The answer: 100000
