Ans : 1600 pounds

Let the weight of tail = t
Let the weight of body = b
Let the weight of head = h

t = 200
h= t+ b/2
b = h+t

By substitution:
h = 200+b/2
2h= 400 + b
2h- b = 400....(1)
b= h+200
h-b = -200....(2)
Subtract (2) from (1)
(1) 2h-b = 400
(2) -h+b = 200
h= 600
And, since,
b= h+200
The fish weighed 200+600+800= 1600 pounds

The answer is 1600 pounds

1600 pounds
