Keith,
Thnk you for your reply but I'm afraid I will have to annoy you once more.
In this specific example I gave - using the 2 DIFFERENT asssumptions does not give you the right answer (you are correct) but it gets you close to the 2 different answers dependant on what assumption you used!
Using Pratts 30 degrees gets you close to answer A
Using Confuser's 25 degrees gets you close to answer B
And B is the correct answer in the Confuser.
So if I get the same type of question again and 2 possible answers come about using either 25 degrees or 30 degrees what should I do!
I agree with the wombat - always aim for 100%.
Sorry keith for badgering you again for info.
I hope the ATPLs are not like this.
