x is the total time given to each contestant to eat. Since the third-place finisher required an average of 15 seconds to consume each hot dog, then he/she ate x/15 hot dogs.

Another solution which does not use that bit of information is here: the-third-place-finisher-of-the-allen-county-hot-dog-eating-134234.html#p1095045

Hope it helps.

The third-place finisher of the Allen County hot dog eating contest, in which each contestant was given an equal amount of time to eat as many hot dogs as possible, required an average of 15 seconds to consume each hot dog. How many hot dogs did the winner eat?

(1) The winner consumed 24 more hot dogs than did the third-place finisher.

(2) The winner consumed hot dogs at double the rate of the third-place finisher.

I thought that I was looking at 700 lvl question..and did not believe it could be that simple...
1 and 2 alone are not sufficient.
1 - we don't know how many hot dogs the third place finisher ate
2 - we don't have any piece of absolute value.

1+2
we have the rate of 1st place, and we have a piece of absolute value

should be sufficient. C

(2) The winner consumed hot dogs at double the rate of the third-place finisher.


From 1 + 2


\(\frac{(X+24)}{(30)} = \frac{(X)}{(15)}\)

15x +360 = 30x
15x=360
x=24

Note : Catch is, we have to equate the times of both contestants.

All the best.

(1) The winner consumed 24 more hot dogs than did the third-place finisher.

(2) The winner consumed hot dogs at double the rate of the third-place finisher.

The goal is to find the number of hot dogs that the winner ate. Incidentally, the average time per hot dog is not actually relevant to the problem.

Statement 1) W = T + 24

The winner ate 24 more hotdogs than the third place finisher. However, we don't know the value of either. Insufficient.

Statement 2) W = 2T. We know this fact is true because the time for each is the same. So if the winner has twice the rate of the third place finisher, then he did twice as much work (eating hot dogs) in the same amount of time. So he ate twice as many hotdogs. However, similar to statement 1, this statement is insufficient.

Statements 1+2) W = T + 24 and W = 2T.

Sufficient. We have two equations and two unknowns.

The third-place finisher of the Allen County hot dog eating contest, in which each contestant was given an equal amount of time to eat as many hot dogs as possible, required an average of 15 seconds to consume each hot dog. How many hot dogs did the winner eat?

(1) The winner consumed 24 more hot dogs than did the third-place finisher.

(2) The winner consumed hot dogs at double the rate of the third-place finisher.


There are several ways to achieve sufficiency in solving this rate problem, so the question cannot be rephrased in a useful manner.

(1) INSUFFICIENT: This statement provides the difference between the number of hot dogs consumed by the third-place finisher (let’s call this t) and the number of hot dogs consumed by the winner (let’s call this w). We now know that w = t + 24, but this does not provide sufficient information to solve for w.

(2) INSUFFICIENT: The third-place finisher consumed one hot dog per 15 seconds. To simplify the units of measure in this problem, let’s restate this rate as 4 hot dogs per minute. Statement (2) tells us that the winner consumed 8 hot dogs per minute. This does not provide sufficient information to solve for w.

(1) AND (2) SUFFICIENT: The rate of consumption multiplied by elapsed time equals the number of hot dogs consumed. This equation can be restated as time = hot dogs/rate. Because the elapsed time is equal for both contestants, we can set the hot dogs/rate for each contestant equal to one another:

w/8 = t/4
w = 2t

Substituting w – 24 for t yields

w = 2(w – 24)
w = 2w – 48
48 = w

The correct answer is C

The winner ate at the rate of double the third place finisher. Which means he ate double quantity compared to third place finisher.

Both were given equal time, as winner ate 24 more, hence he ate 48. double of 24.
