Directions: Study the following information carefully and answer the questions given below.
There are five groups [X, Y, Z, W, and V]. Each group consists of six members: Veteran Member, Senior Member, Leader, Deputy Leader, Junior Member, and Youngest Member (arranged in the decreasing order of their ages). The following table provides details about the age of the Veteran Member, the ratio of the ages of the Veteran Member and the Senior Member, the ratio of the ages of the Leader and the Deputy Leader, the age of the Youngest Member, and the age of the Junior Member. Some values in the table are missing.
| V | W | Z | Y | X | |
| The age of the Youngest Member | ----- | ----- | 20 | ----- | 18 |
| The age of the Junior Member | 27 | ----- | 25 | 22 | ----- |
| The ratio of the ages of the Leader and the Deputy Leader | 15:14 | 16:14 | ----- | ----- | ----- |
| The ratio of the ages of the Veteran Member and the Senior Member | ----- | 15:16 | ----- | 21:20 | ----- |
| The age of the Veteran Member | 80 | ----- | ----- | ----- | 72 |
The ratio of the ages of the Youngest Member and Junior Member of Group Y is 12:11. The sum of the ages of the Youngest Member and the Veteran Member in Group Y is (25 × 4 + 8) years. The age of the Deputy Leader is 3 years older than 56.25% of the age of the Senior Member. The age of the Leader is 2 years less than the age of the Deputy Leader. If the difference between the ages of the Leader and the Veteran Member is x, what is the possible difference between the ages of the Youngest Member and the Junior Member?
I. (x / 19)
II. 0.4x - 13.2
III. 0.9x - 32.4
