The Mystery of Carol and Her Father's Ages

[bindwood]

carol's age in years, can be expressed by reversing the digits in her father's age, in years. the sum of the digits in each age is 10.
the positive difference between carol's age in years, and her fater's age in years___36
a.>
b.<
c.=
d.uncertain

In my opinion, there are four pairs: (19,91),(28,82),(37,73),(46,64). the differences are 72,54,36,18 respectively. so I choose d. But the answer is b, I was confused. Am I wrong or the answer is incorrect? Can you throw some ideas? Any help would be much appreciated.

Please don't "double post" homework questions. The same question has been answered in your earlier thread, albeit four minutes later than the current one.

I would approach this problem by first clarifying the given information. It is stated that Carol's age is expressed by reversing the digits in her father's age, and the sum of the digits in each age is 10. However, it is not specified whether the sum of the digits in Carol's age is also 10. This could potentially lead to multiple solutions.

Based on the information given, it is possible to come up with multiple pairs of ages that fit the criteria. The pairs (19,91),(28,82),(37,73),(46,64) all have a sum of digits equal to 10 and the difference between the two ages is 72, 54, 36, and 18 respectively. Therefore, it is uncertain to determine the exact ages of Carol and her father without additional information.

In order to accurately answer the question, we would need to know the specific sum of digits in Carol's age. Without this information, it is impossible to determine whether the correct answer is b) < or d) uncertain. It is important to always consider all the variables and information given in order to come to a conclusive answer in scientific research.
