I know this is a really stupid question.
The reason I'm asking is I made a little bet with my brother and I'm
not sure I have to pay up.
The bet was in which system would a normal 110V 10Amp breaker blow
first.

System 1 - assuming each toaster draws 1Amp and runs at 110V - the voltage on the system is 110V I plug 10 of them in, breaker is OK, plug in #11, breaker should blow

System 2 - assuming each toaster draws .5Amp and runs at 220V - the voltage on the system is 220V How many toasters can I plug in until the EXACT same breaker will blow in this system?

I appreciate your indulgence on this silly question.
