The group policy is to amortize goodwill over 5 years. S was acquired in X2
During the year, nca of nbv RM750,000 were sold for RM850000

I would like to ask how to calculate the dividend paid by S to NCI and dividend paid by SS to NCI in this question?

Besides, The group policy is to amortize goodwill over 5 years. S was acquired in X2
for the sentence above what does it useful because the cash flow is do for X5 so how do we know the impairment of goodwill is how much for S?
