Scheweser Mock, Exam-2 (PM)- Volume 2- FRA

From Scheweser (Afternoon) Mock session- Volume-2 Exam-2, does anybody know how long term debt to equity has been calculated in the solution under the Acquisition method.

Actually, in the equity calculation, the solution adds non-controlling interest (NCI)- correct, but how do you calcuate NCI…based on whats given in the vignette…since the fair value of acquisition is not given (which is how NCI has been calculated in the curriculum )

Any thoughts?
