State whether Ed has any right of action against Ace Ltd for the work that he did in solving the Brag problem
【参考答案及解析】
an offeror may revoke their offer at any time before acceptance. However this is not the case in unilateral contracts and revocation is not possible once the offeree has begun to perform the task specified in the offer. Ed is an employee and therefore included in the terms of the offer. Ace Ltd is not permitted to revoke the offer and therefore since he solved the problem before the deadline Ed is entitled to the reward.
