1. a) Every week, Amy and Jim and their daughter, Sophie, enter the National Lottery, each contributing £1 for 3 lucky dip numbers. Sophie always fills in the form, pays over the money to the newsagent, and keeps the ticket. Last week five of their numbers came up and the ticket paid out £5,000. Sophie refuses to share the £5,000. Advise Amy and Jim.

b) Discovering the kitchen on fire, Bella telephoned the fire brigade. On their arrival she told Sam, the officer in charge, that she would give each fireman £50 if they prevented the fire from damaging her living room which contained valuable antiques. The firemen extinguished the fire and confined its effects to the kitchen. Bella has refused to pay. Advise the fire brigade.

c) Alice is travelling to Oxford when her car gets a puncture. The driver of a passing van stops and offers to change the wheel of Alice’s car. When he has finished he says ‘That will be £100 please. I’m part of the Blue Flag rescue service. I have a garage just down the road.’ Explain to Alice if she is legally obliged to pay the £100.

d) While Paul is away on holiday his neighbour, Jim, mends Paul’s garden fence. When Paul returns he is so pleased he promises to give Jim a case of French wine. This was two weeks ago and Jim has still not received any wine. Has a contract been made between Paul and Jim?
