Kobus has a dilemma, he has a bad back, no trolley or a helping hand, but he wants to move a keg of beer from his pub, to his Ford so that he can take it to a rugby match/ braai at his mates house. The keg of Castle Draught weighs 30kg. What must he add to the keg to make it weigh 15kg so that it is light enough to pick up?
