How to get a single output for two different statements using sql

SELECT class,
       COUNT(*) total,
       COUNT(p.studentid) purchased,
       COUNT(*) - COUNT(p.studentid) remaining
  FROM student_table s LEFT JOIN
       purchase_table p ON s.studentid = p.studentid
 WHERE s.class = '1A'
GROUP BY class;

SELECT CASE WHEN M.DispOrd=1 THEN 'CLASS '+ M.Class 
	    WHEN M.DispOrd=2 THEN 'TOTAL NO OF STUDENTS '+ M.Class + ' ' + CAST(M.Count AS VARCHAR(10))
	    WHEN M.DispOrd=3 THEN 'STUDENTS PURCHASED '+ M.Class + ' ' + CAST(M.Count AS VARCHAR(10))
	ELSE 'REMAINING STUDENTS '+ M.Class + ' ' + CAST(M.Count AS VARCHAR(10)) 
	END 'Result'
FROM (SELECT DISTINCT Class,NULL 'Count, 1 'DispOrd'
     FROM Student_Table
     UNION ALL
     SELECT Class ,COUNT(StudentID), 2
     FROM Student_Table
     GROUP BY Class
     UNION ALL
     SELECT Class, COUNT(StudentID), 3
     FROM Purchase_Table 
     GROUP BY Class
     UNION ALL
     SELECT T.Class,T.Count, 4
     FROM (SELECT S.Class, COUNT(S.StudentID)-COUNT(P.StudentID)
           FROM Student_Table S
       	   LEFT OUTER JOIN Purchase_Table P On P.studentID=S.StudentID
           GROUP BY S.Class) T
     ) M
ORDER BY M.Class, M.DispOrd
-- Note : Check the Syntax bcos I don't have SQL server in my machine :-)
