Idle spent his afternoon in the great city yesterday, being entertained by one of the world's largest fund managers.
They started us off with an amusing talk by a fellow called Montier who is a behavioural scientist and makes a living in the city by forecasting index movements according to his knowledge of herd activity, overconfidence etc.
Some of his examples were interesting. Here are some easy questions; see how you do when the answers come up later. DON'T READ THE COMMENTS UNTIL YOU HAVE ANSWERED THEM.

2. A bat and a ball cost $1.10 in total. The bat costs a dollar more than the ball. How much does the ball cost?
