This might help you....

SELECT D.BLOCK_NAME, C.PNAME, SUM(A.ENROLLED),SUM(A.PERSONALIZED),SUM(A.CARDHOLDER), COUNT(A.FAMILY_ID)-COUNT(B.FAMILY_ID)
FROM Txnenrollment A
LEFT OUTER JOIN Txnissuance B ON A.FAMILY_ID=B.FAMIL_ID
JOIN mstpanchayat C ON C.PCODE=A.PCODE
JOIN mstblock D ON D.BLOCKCODE=A.BLOCKCODE
GROUP BY D.BLOCK_NAME, C.PNAME

pcode is primary key in mstpanchayat,
blockcode is primary key in mstblock
and pcode and blockcode exists in txnenrollment
and txnissuance will have only those familyid
which will exist in txnenrollment and will have status of enrolled=1 and personalized=1 and cardsprinted=1
