Explanation:
Initial Average of Class E:
- Let's assume the initial average of class E is x.
Transferring 5 people from E to R:
- If 5 people are transferred from E to R, the total number of people in E decreases by 5 and the total number of people in R increases by 5.
- As the average of class E is x, the total sum of marks in class E before transfer is 5x.
- After transferring 5 people to R, the total sum of marks in class E becomes 5x - 5.
- Therefore, the new average of class E becomes (5x - 5)/(x - 5).
Transferring 5 people from R to E:
- Another independent set of 5 people are transferred back from R to E.
- As per the condition, this set does not contain any student from the previous set of 5 people transferred from E to R.
- Therefore, the total sum of marks in class E after this transfer becomes 5x - 5 + 5 = 5x.
Final Average of Class E:
- The total number of people in class E remains the same after the second transfer, which is 5.
- Therefore, the final average of class E after both transfers is 5x/5 = x.
Minimum Possible Average:
- As we want to find the minimum possible average of class E, we need to find the minimum value of x.
- Since the initial average of class E is x, the minimum possible value of x can be when x = 20.
- Therefore, the minimum possible average of class E at the end of the operation is 20.
Therefore, the correct answer is option B) 20.25.
