The Future perfect tense is primarily employed to denote an action that will have been accomplished or completed before a specific time in the future. Such action is expected to be perfected before that time. The sentence in the future perfect tense is framed using 'subject + 'will have' + past participle form of the verb.' The use of 'will' denotes future and 'have' helps in expressing the perfection of the action. Thus, as per this rule, the above sentences are framed by conjugating the verb 'to know' with the given subjects.
