THE BANK

SOME ROBBERS WANT TO ENTER INTO A BANK.

THEY NEED TO DIGIT A PASSWORD.

THEY ONLY KNOW THAT:

• IF THE DISPLAY SHOWS 6, THEY MUST DIGIT 3;
• IF THE DISPLAY SHOWS 24, THEY MUST DIGIT 12;
• IF THE DISPLAY SHOWS 10, THEY MUST DIGIT 5;
• IF THE DISPLAY SHOWS 8, THEY MUST DIGIT 4.

WHEN THEY ARE IN FRONT OF THE DOOR, THE DISPLAY SHOWS 20.

WHICH NUMBER SHOULD THEY DIGIT AND WHY?


PAY ATTENTION:

THERE ARE TWO POSSIBLE SOLUTIONS!!!

CAN YOU FIND THEM BOTH???

POST ME YOUR SOLUTION ;)
