kcjenkins Posted April 1, 2008 Report Share Posted April 1, 2008 A trout's tail weighs eight pounds. Its head weighs as much as the tail and one-half of the body combined, and the body weighs as much as the head and tail combined. What does the whole trout weigh?

Dan Posted April 1, 2008 Report Share Posted April 1, 2008 1. Tail = 8 lbs. 2. Head = 24 lbs. 3. Body = 32 lbs. Total is 64 lbs. h = head (h = 8 + 1/2b) t = tail (t = 8lbs.) b = body (b = h + 8) h = 8 + 1/2 (h + 8) h = 8 + 1/2h + 4 h = 12 + 1/2h h - 1/2h = 12 1/2h = 12 h = 24 Quote Link to comment Share on other sites More sharing options...

indyscott Posted April 2, 2008 Report Share Posted April 2, 2008 What was wrong with Dan's answer? Linda didn't even show her work. I think maybe she copied off of Dan! ;) Quote Link to comment Share on other sites More sharing options...

I think Dan went back and edited his answer after I posted mine, his first answer was different and did not show the work. Quote Link to comment Share on other sites More sharing options...

Dan Posted April 3, 2008 Report Share Posted April 3, 2008 LindaB Yes, I edited my post but it was before I saw your post. After adding the reply, I looked to see how others had responded to the brain test. That is when I saw that you had the same answer. I put the formula down to show anyone that visited the post, how I got the answer. Quote Link to comment Share on other sites More sharing options...

LindaB Posted April 3, 2008 Report Share Posted April 3, 2008 I still think there's something fishy going on.. Later I was trying to think what the rule was---that you could solve for 3 variables if you had 3 equations, I think. I tried to solve again pretending that I didn't knowing the tail was 8 pounds, but just went round and round with the equations. It would only come up with a 'blueprint' for a fish that could be any size, but proportional to this fish. Quote Link to comment Share on other sites More sharing options...
