3 Cubes - each contains keyfigure K1 - what value will be shown?

Hello

I have got a multicube, which is based on 3 infocubes C1, C2 and C3.

C1, C2 and C3 all contains keyfigure K1. And K1 is selected in the multicube for all 3 infocubes.

My question is then. If the value of K1in C1 and C2 are "50" and in C3 are "45". What K1 value will then be shown in a query that is based on this multicube?

Thanks in advance
