A problem from NMCC final 2017
A strange bank account
In Nordic Bank it is only possible to insert 6 €
or withdraw 11 € every time you go to the bank.
Example
Alice first inserts 6 €, then another 6 €, and yet another 6 €.
Next time she withdraws 11 €.
She then has 7 € on the account.
Now you have to investigate
- Which other amounts is it possible for Alice to have in her account?
- Which amounts could Alice have in an account where it is only possible to insert 6 € and to withdraw 14 €?
