Answer 1

Answer : D

Average salary of male employee is more than the average salary of the organization

select deptName 
from Employee 
where sex = 'Male'
group by deptName
having avg (salary) >   
(select avg (salary) from Employee)

Here we are going to get the name of all departments in which the average salary of male employees is greater than the average salary of all employees in the company.
