Kaplan exam kit question, not enough information?

Hi, I’m having an issue with a multi task question from the Kaplan exam kit (pg159)
Pike and Salmon – Pike acquired 75% of the issued share capital of Salmon on 01/01/06 for 8.72 million. Also Pike invested 1million of Salmons 5% loan notes at par value. Financial statements at 31/03/06
Equity

Retained earnings –

Salmon
Share Capital –
Retained earnings – 1,290,000

Pike
Total equity – 21,680,000
Salmon
Total equity – 6,090,000

Non-current liabilities
Pike
5% loan notes 2009. 16,440,000
Current Liabilities 2,640,000
Salmon
5% loan notes 2009. 11,180,000
Current Liabilities 1,410,000

– At acquisition, fair value of land owned by Salmon exceeded cost by 1,000,000, still owned at 31/03/06

-During post-acquisition period, Salmon sold goods to Pike for 500,000, on which it earned a margin of 10%. 80% of the goods remained in inventory at year end and Salmon owed half of the total amount to Pike.

-Fair value of the non controlling interest in Salmon at the date of acquisition was 2.4 million

– For year end 31/03/06, Salmon made a profit after tac of 240,000

How do we calculate the fair value of net assets of Salmon at the date of acquisition? The three options say 4,800,000 + ……, but I don’t understand where this figure comes from?

Thanks!!!
