How are you getting all these questions?????

Well, there are 7C1 = 7 ways for the chairmen.

6C2 = 15 ways to choose two deputies (2 deputies out of 6 remaining people).

4C2 = 6 ways to choose two assistants (2 assistants out of 4 remaining people)

Multiplying them: 15*6*7 = **630 different ways.**
