Reasoning and answer: His total speed from the trials is 108 because 36 + 34 + 38 = 108. His average speed was 36 mph because 108 / 3 = 36. He needs to go 4 mph faster to make it to the top because 40 - 36 = 4.
The answer: 4

Ivan spent a total of $10 - $3 = $7 on cupcakes and a milkshake. The cost of the cupcake is $10 x 1 / 5 = $2. So, $7 - $2 = $5 was spent on the milkshake.
The answer: 5
Reverse engineering the question: Ivan had $10 and spent 1/5 of it on cupcakes. He then spent some money on a milkshake and had only $3 left. How much is the milkshake?


Reasoning and answer: Since barbara needs $100, and she currently has $20, she is remaining with $100 - $20 = $80 to save. With an allowance of $5 each week, she'll need to save for 80 / 5 = 16 weeks.
The answer: 16

Since 6 women are 20% of the total number of women working there, that means there are 6 * 5 = 30 women working there in total. Since there are an even number of women and men working in the office, that means there are 30 * 2 = 60 people working there in total, since there are 2 sexes.
The answer: 60
Reverse engineering the question: Ryan works in an office that has an even number of men and women working there. Ryan participates in a meeting composed of 4 men and 6 women who are pulled from the office floor.  This reduces the number of women working on the office floor by 20%. How many people work at Ryan's office?


Reasoning and answer: Since Rick and Jose's lunch cost was the same, Adam spent 2 / 3 * 45 = $30 on his lunch. The three friends ate food worth 30 + 45 + 45 = $120.
