Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference between R and Q’s age?
🤔 Age Difference Puzzle 🤓
Let’s break it down step by step:
Let Q’s age be x.
Since Q is as much younger than R as he is older than T, we can set up the following equation:
R – x = x – T
Simplifying the equation:
R + T = 2x
We know that the sum of R and T’s ages is 50:
R + T = 50
Substituting this into the previous equation:
50 = 2x
Dividing by 2:
x = 25
So Q’s age is 25.
Now, let’s find the difference between R and Q’s age:
R – Q = R – 25
We don’t know R’s exact age, but we can express it in terms of T:
R + T = 50
R = 50 – T
Substituting this into the previous equation:
(50 – T) – 25
Simplifying:
25 – T
Since T’s age is unknown, the difference between R and Q’s age can be any value.
However, we can determine the range of possible differences:
The maximum difference occurs when T is 0 (which is not possible in reality, but let’s consider it for the sake of calculation):
25 – 0 = 25
The minimum difference occurs when T is 25 (which would make Q and T the same age):
25 – 25 = 0
Since we’re looking for a definite difference, we can conclude that:
The difference between R and Q’s age is at least 5 years.
This is because the minimum possible age for T is 0 (which is not realistic), and the maximum possible age for T is 25. Any value of T between 0 and 25 would result in a difference of at least 5 years.
However, without knowing the exact ages of R and T, we cannot determine the exact difference.
But we can say that the difference between R and Q’s age is at least 5 years, and at most 25 years.
