Reasoning and answer: Let the number of blind students be x. The number of deaf students will then be 3 * x = 3x students. The total number of students is x + 3x = 180 students. Combining like terms gives 4x = 180. So the value of x is 180 / 4 = 45.
The answer: 45

Tony paid $7 - $5 = $2 more than Arnold. We know he bought the same number of bananas as Arnold but that he bought 2 - 1 = 1 dozen apples more than Arnold. Therefore a dozen apples should cost $2. If Arnold paid $5 and $2 for a dozen apples then the bunch of bananas cost $5 - $2 = $3.
The answer: 3
Reverse engineering the question: Tony paid $7 for 2 dozen apples and 1 bunch of bananas. Arnold paid $5 for 1 dozen apples and 1 bunch of bananas. How much does a bunch of bananas cost?

There are 3 groups * 25 people / group = 75 people in total. There are 14 girls + 11 boys = 25 children in total. There are 75 people - 25 children = 50 parents.
The answer: 50
Reverse engineering the question: There are 14 girls, 11 boys, and their parents at a park. If they split into 3 equally sized playgroups, each group contains 25 people. How many parents were at the park?
Reasoning and answer: Jolyn is 2 + 5 = 7 months older than Aivo. Since Leon is 2 months older than Aivo, then Jolyn is 7 - 2 = 5 months older than Leon.
The answer: 5
What was the question?
Question: Four classmates were comparing their ages based on their birth month. They found out that Jolyn is 2 months older than Therese while Therese is 5 months older than Aivo. Then, Leon is 2 months older than Aivo. How much older in months is Jolyn than Leon?
Reasoning and answer: If 50% of individuals that like football play it, and there are 24 out of 60 individuals that like it, then 24 * 50% = 12 out of 60 individuals play it. If 12 individuals play it out of 60 individuals then that means only 12 / 60 = 1 / 5 or 20% play it. If 20% of individuals play football out of a group of 250 people, one would expect 250 * 20% = 50 individuals to play it.
The answer: 50
