George has 3 bottles - A, B and C which hold 3,5 and 8 litres respectively. Water is scarce so George isn't allowed to throw out any but he can fill the bottles up using the tap as often as he likes. Filling the bottles using the tap does not count as a transfer.
What is the minimum number of water transfers from the bottle to bottle that George has to make to acquire exactly four litres?
PLEASE ANSWER just so that i can feel that i've triumphed over the LMS for a change since it's been kicking me in the ass for the past month or so ='(
