D-Group Structure - Example 3 - Kallis, Steyne, Adam

Hi Sir, This is with reference to Example 3, of the Complex Group - D Shaped structures. The NCI at acquisition for Steyn in the answer to the Question is given as 10 million. But in the question, it is given as 25 million. Can you please tell me if this is a typo error or am I doing something wrong by putting in the NCI at 25 million for Steyne (the subsidiary) Thank you sir.
