Change in a group structure

P purchased 80% of the shares in S 4 yrs ago for $100,000. On 30 June it sold all of these shares for 250,000. The nest assets of S at the acq’n date were $69,000 and at the DOD were $88,000. 50% of the goodwill arising on acq’n had been written off in an earlier year. The FV of NCI in S @DO A was $15,000. It is grp policy to account for goodwill using the full goodwill method.

Tax is charged at 30%

Calculate the profit or loss arising to the grp on the disposal of the shares.

I did :
Proceeds of disposal. 250
NA @ DOD. 88
% sold. 80% (70.4)
Goodwill sold. ( 23)
Gain in group. 156.6
Tax. (45)
111.6

I’m not getting the answer I’m suppose to….I know I made a simple mistake but I can’t put my finger on it…..could you please help me to clarify this issue thanks.
