there are several teams and each team send 3 participants
Alex scored high than bob... rank of Alex greater than bob(means 18,17,16.....) and score of Alex = medium of all the scores of participants
the rank of bob= 19
the rank of Cathy = 28
we can solve this by evaluating answer choices one by one
A. 6
if there were 6 teams then the total number of
participants would be = 6*3 = 18 (if there are 18 participants how could Cathy get 28th rank so the number of participants must be greater than 18)
