Explanation

Set up your ratio box.

The number given is the actual total number of players, so put 24 there.

Then start Plugging In the Answers into your ratio row to see which could work.

The ratio of 1:2 in choice A would yield a ratio total of 3; this works with a multiplier of 8, so you know choice
(A) works.

Choice B gives a ratio total of 4, which would work with a multiplier of 6; choice B works.

Choice C, however, gives a ratio total of 5; since 24 isn’t a multiple of 5, it would yield a fractional multiplier, and thus fractional juniors and seniors. Eliminate choice C.

Choices D and E would work with multipliers of 4 and 3, respectively.

Choice F yields a ratio total of 11, which will again yield a fractional multiplier, so eliminate choice F.

Hence options A, B, D and E are correct!
