Solution

Number of competitors in the race = 12
Number of  competitors who can come first in the race = 12
Number of  competitors who can come second in the race = 11    (as one competitor has already come first in the race)
Number of  competitors who can come third in the race = 10
∴ Total number of ways of awarding the first three prizes = 12\[\times\]11\[\times\]10 = 1320
