intercorporate investments, Q please

I have a q on intercorporate investments, for the acquisition method, schweser says stockholders equity stays the same, but q #3 in CFA says that under the acquisition method that SHE is highest because it includes minority interest, So what is correct?

there is an entire errata on this, acquisition is highest and equity/proport consolidation is roughly equal

is that a correction to schweser or to CFAI materia?
