Calculating the maximum average of class R after the transfers:
- Initially, let's assume the average age of class R is 'x'.
- After transferring 5 people from E to R, the total number of people in R increases by 5.
- Now, after transferring 5 people back from R to E, the total number of people in R remains the same as before.
- However, the total age in class R has increased as the 5 people transferred from E to R are older than the 5 people transferred back.
- This means that the average age of class R has increased after the transfers.
Finding the maximum possible average:
- Let's assume the average age of the 5 people transferred from E to R is y.
- Since these 5 people are older than the average age of class R, y > x.
- Now, after transferring these 5 people back to E, the average age of class R will increase by (y - x)/5.
- To maximize this increase, we need to maximize the value of y.
- The maximum value of y can be achieved by making it equal to the maximum possible age in the group.
- Therefore, the maximum value of y is the maximum possible age of a person in the group.
- Hence, the maximum possible average of class R after the transfers is x + (maximum possible age - x)/5.
Conclusion:
- The correct answer is option 'D' (24.8), as it represents the maximum value of the average age of class R after the transfers.
- Initially, let's assume the average age of class R is 'x'.
- After transferring 5 people from E to R, the total number of people in R increases by 5.
- Now, after transferring 5 people back from R to E, the total number of people in R remains the same as before.
- However, the total age in class R has increased as the 5 people transferred from E to R are older than the 5 people transferred back.
- This means that the average age of class R has increased after the transfers.
Finding the maximum possible average:
- Let's assume the average age of the 5 people transferred from E to R is y.
- Since these 5 people are older than the average age of class R, y > x.
- Now, after transferring these 5 people back to E, the average age of class R will increase by (y - x)/5.
- To maximize this increase, we need to maximize the value of y.
- The maximum value of y can be achieved by making it equal to the maximum possible age in the group.
- Therefore, the maximum value of y is the maximum possible age of a person in the group.
- Hence, the maximum possible average of class R after the transfers is x + (maximum possible age - x)/5.
Conclusion:
- The correct answer is option 'D' (24.8), as it represents the maximum value of the average age of class R after the transfers.
