Let us assume the weight of the red snapper caught by Dana = X

The weight of the tuna caught by Jason was 3 times the weight of the snapper caught by Dana. Then,

Weight of the tuna caught by Jason = 3X

Weight of the sailfish caught by Murray is 12 times the weight of the red snapper caught by Dana. Then,

Weight of the sailfish caught by Murray = 12X

The combined weight of the 3 fishes caught = 208 pounds.

Then,

X + 3X + 12X = 208

16X = 208

X = 208/16

= 13

So the red snapper weighed 13 pounds

The weight of the tuna caught by Jason = 3X

= 3 * 13

= 39

So the tuna weighed 39 pounds.
