I did not get the meaning of 'Two of the employees sit on either side of the table.' If two of the employees sit on either side of the table then how is it 4!?

It seems to me they want us to get confused.

'Two of the employees sit on either side of the table.' It means nothing in this case.
So what? It is the same as 4 workers and 4 seats. So 4! ways.

Two of the employees have to sit on one particular side of the table. Different meaning - different answer.
Two of the employees have to sit one next to another. Different meaning - different answer.

What is good. There are no answer options that suit to these conditions. So it is impossible to make mistake.

1 question & 1 point:

1) For regular employees, if we have 4 different employees and 4 seats, shouldn't it be 4 seats * 4 employees=16 to get number of combinations? I've definitely seen that before. Like if you have 5 food options and 4 drink options you have 5*4=20 choices.

2) I guess we are supposed to assume that M can only sit in one spot instead of their being 2 ends of a table. Seems a bit ambiguous.

Thank you.

Since the manager must sit at the head of the table, there are 4 chairs left. There are 4 choices for the first chair, 3 choices for the second, 2 choices for the third and 1 choice for the fourth. Therefore, the number of seating arrangement is:

4 x 3 x 2 x 1 = 4! = 24

Answer: C
