When maths and sausages collide.

Sign in a shop on Tottenham Court Road: 'XXXX Sausages - now with 50% more meat!' You see, what they've done there is over-reached themselves. 10% more meat sounds quite good. Even 20%. But 50% more meat... frankly, there shouldn't have been that much room for improvement in the old sausages. They must have been at the most only 66.6% meat... and not even that, because if they were the signs would now say 100% meat. Which they don't. And suddenly the possibility that they were, say, 10% meat, and are now a mighty 15%, starts seeming horribly plausible...
