which returns the number of employees whose age is 27, and the other contains the single UPDATE statement

The granular locking protocol can exhibit a deadlock between two transactions, one of which executes a single SELECT statement and the other a single UPDATE statement. For example, suppose that one transaction contains the single SELECT statement

SELECT COUNT (P.Id)
FROM Employee P
WHERE P.Age = ’27’
UPDATE Employee
SET Salary = Salary * 1.1
WHERE Department = ’Adm’
which gives all employees in the administration a 10% raise. Assume that there are indices on both Department and Age and that the tuples corresponding to the department Adm are stored in more than one page as are those corresponding to age 27. Showhowa deadlock might occur at isolation levels other than READ UNCOMMITTED.
