Try this:
WITH ac_bank_amt_dtl AS
(SELECT 'DEPOSIT' payment_type, 'STATE BANK OF INDIA' bank_name, 12000 amount FROM dual UNION ALL
SELECT 'DEPOSIT' payment_type, 'ICICI BANK' bank_name, 15000 amount FROM dual UNION ALL
SELECT 'WIDRAW' payment_type, 'ICICI BANK' bank_name, 1200 amount FROM dual UNION ALL
SELECT 'DEPOSIT' payment_type, 'ICICI BANK' bank_name, 12000 amount FROM dual UNION ALL
SELECT 'DEPOSIT' payment_type, 'STATE BANK OF INDIA' bank_name, 34000 amount FROM dual)
SELECT   bank_name,
         SUM(CASE payment_type
             WHEN 'DEPOSIT' THEN amount
             WHEN 'WIDRAW' THEN -amount
             END) balance
FROM     ac_bank_amt_dtl
GROUP BY bank_name
