Hi guys, I have scanned the question as its easier than typing it out and put it online here (sorry its kinda bad quality):

If you guys cant see the image properly then tell me and I will try and clarify the problem.
Ok so my answers for question (i) is
I3 = 1 + (19/12)A
I2 = 1 + (5/4)A
I1 = 1 + (1/4)A
Is this right?
My answer for question (ii) is
A = 12
But can somebody show me how they would show that A = 12, if that is actually the right answer, and if not what is the right answer and how to get to it.
Thanks in advance
