Twenty-one employees hold different designations in a bank: CEO, MD, DGM, AGM, Manager, and Clerk. The hierarchy from senior-most to junior-most is CEO > MD > DGM > AGM > Manager > Clerk. The number of employees at each designation is exactly one more than the number at the immediately senior designation. For example, if there are 3 AGMs, then there are 4 Managers, and so on.

Given:

• P, T, and W share the same designation.
• S is senior to W.
• X is senior to U, who is not an AGM.
• R and V share the same designation.
• Neither B nor H is a Manager, but both share the same designation.
• D, E, and H share the same designation, which is junior to Q and T.
• Q is junior to U.
• The number of persons senior to Q and T is the same.
• X is junior to N but senior to R.
• A, L, and M share the same designation.
• W is not a Manager.
• R is neither Manager nor Clerk.
• Z and Y are senior to G and O.

These employees are transferred to three departments: HR, Marketing, and Legal, based on the following rules:

I. No transfers for the top two designations; they become leaders of HR, Marketing, and Legal respectively in alphabetical order.

II. Employees whose names start with a consonant before 'M' in the alphabet go to HR.

III. Employees whose names start with a consonant after 'M' go to Marketing.

IV. The rest go to Legal.

Question: How many employees are transferred to the Legal department?
