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 €?
