Duncan Disorderly had a collection of Des O Connor records (vinyl 45’s for those who remember them) which he wished to sell. He sold half of his records plus a half record more to Professor Tonedef; then he sold half of what was left and a half record more to Whistling Willy. At this point Duncan had one record left. How many records did Duncan have originally?
