Answer:

773 salmons

Explanation:

Total number of salmon caught by fishermen = 60

Total number of tagged salmon caught = 20

Percentage of tagged salmon in the sample = 20/60 x 100 = 33.33%

255 tagged salmon constitutes 33.33% of the entire salmon population

If the entire population is represented by X

255 = 33/100 of X

X = 255 x 100/33

X = 772.7

Hence, the salmon population in the lake is approximately 773.
