Sample Solution:

SELECT JobTitle, MAX(ph1.Rate)AS MaximumRate  
FROM HumanResources.Employee AS e  
JOIN HumanResources.EmployeePayHistory AS ph1 ON e.BusinessEntityID = ph1.BusinessEntityID  
GROUP BY JobTitle  
HAVING (MAX(CASE WHEN Gender = 'M'   
        THEN ph1.Rate   
        ELSE NULL END) > 40.00  
     OR MAX(CASE WHEN Gender  = 'F'   
        THEN ph1.Rate    
        ELSE NULL END) > 42.00)  
ORDER BY MaximumRate DESC;

Sample Output:
