Given Information:
The average age of all the 20 students of a class is 24.
The minimum age of a student is 18 and the maximum age of another student in the same class is 30 years.
Two students with an average age of 26 years were removed from the class.

Calculating Initial Total Age:
Total age of all 20 students = 20 * 24 = 480

Calculating Total Age of the Two Students:
Total age of the two students = 2 * 26 = 52

Calculating Total Age of Remaining Students:
Total age of the remaining 18 students = 480 - 52 = 428

Calculating Average Age of the Class Now:
Now, one of the two removed students is readmitted, so the total number of students is 19.
Let the age of the readmitted student be x.
Therefore, the new total age of all 19 students = 428 + x
The average age of the class now = (428 + x) / 19

Solving for x:
Given that the minimum age is 18 and the maximum age is 30, and the average age is 24 for 20 students.
Hence, the total age of the two students who left can be calculated as:
(18 + 30) - 2 * 24 = 48 - 48 = 0
This means the sum of the two students' ages is equal to the sum of the ages of the readmitted student and the remaining 18 students.
Therefore, the age of the readmitted student, x = 48.

Final Calculation:
The new total age of all 19 students = 428 + 48 = 476
Therefore, the average age of the class now = 476 / 19 ≈ 25.05 years.
