There may be 1, 2, 3, 4, ..., 8, or 9 companies.
The organizers have to allocate slots so that each company will have the same number of slots.

Hence, number of slots = LCM of 1, 2, 3, 4, ..., 8, and 9 = 9*8*7*5 = 2520

The correct answer is E.

The answer should be able to evenly divide numbers 1 through 9
only option E does that.

The least time consuming method to solve this problem is to check the options for a number divisible by 9.

If a number is divisible by 9, the sum of the digits of the number will be divisible by 9 too.
  • (A)20 --> (2 + 0) = 2 --> NO
    (B)60 --> (6 + 0) = 6 --> NO
    (C)420 --> (4 + 2 + 0) = 6 --> NO
    (D)840 --> (8 + 4 + 0) = 12 --> NO
    (E)2520 --> (2 + 5 + 2 + 0) = 9 --> YES
The correct answer is E.

The question stem should ask for the LEAST number of slots that must be allocated.

Each company that attends must be given the same number of slots.
Since 9 companies could attend, the correct answer choice must be a multiple of 9.
For an integer to be a multiple of 9, the SUM OF ITS DIGITS must be a multiple of 9.
Of the answer choices, only E works:
2+5+2+0 = 9.

The correct answer is E.
