Whereas the account A00024 has done 3 transactions i.e. suppose 2 withdrawals and 1 deposit. So account number of A00023 should be displayed.

Problem #2:

Write a query to show the branch name,branch city where we have the maximum customers. For example the branch B00019 has 3 customers, B00020 has 7 and B00021 has 10. So branch id B00021 is having maximum customers. B00021 is suppose for Koramangla branch Bangalore. So Koramangla branch should be displayed along with city name Bangalore.

Problem#3:

Write a query to show the balance amount for account number A00001.

Note: Balance amount includes account opening balance also. For example A00015 is having an opening balance of 1000. A00015 has deposited 2000 on 2012-06-12 and deposited 3000 on 2012-07-13. The same account has drawn money of 500 on 2012-08-12 , 500 on 2012-09-15, 1000 on 2012-12-17. So balance amount is 4000 i.e (1000 (opening balance)+2000+3000 ) â€“ (500+500+1000).

Problem # 4:

Write a query to display all those account number, deposit, withdrawal where withdrawal is more then deposit amount. For example A00011 deposited 2000 rupees on 2012-12-01 and 3000 rupees on 2012-12-02. The same account i.e A00011 withdrawn 3000 rupees on 2013-01-01 and 7000 rupees on 2013-01-03. So the total deposited amount is 5000 and total withdrawal amount is 10000. So withdrawal amount is more then deposited for account number A00011.

Problem # 5:

Write a query to display the customer number, firstname, lastname for those client where total loan amount taken is maximum and at least taken from 2 banks. For example the customer C00012 took a loan of 100000 from bank branch with id B00009 and C00012 Took a loan of 500000 from bank branch with id B00010. So total loan amount for customer C00012 is 600000. C00013 took a loan of 100000 from bank branch B00009 and 200000 from bank branch B00011. So total loan taken is 300000. So loan taken by C00012 is more then C00013.
