S represents the sum of the weights of n fish in pounds. Which of the following represents the average (arithmetic mean) of the n weights in ounces? (1pound = 16 ounces)
As the sum of n fish in pounds is S pounds and 1 pound = 16 ounces then the sum of n fish in ounces will be 16S ounces.
So, average wight of n fish in onces is average=(sum of weights is ounces)/(# of fish)=16S/n.

It's very clear. Not sure why this one even held me up. Think it was one of those long study nights where even the mundane and easy seem like a never ending brick wall that you are trying to climb. Thanks Bunuel. +1 buddy and kudos.

Bunuel, how can we plug in numbers for this one? This one looks simple, but for some reason, I'm having a hard time seeing if I'm doing it correctly...
Is this right? n = 3 (for 3 fish) s = 3 (each fish to weight 1 pound each. There are 3 fish so this equals to 3 pounds (total)).
Plugging into answer choice B) 16(3)/3 = 16 (since 16 is the average weight of the fish in ounces).
