People are just reading it to mean what they want it to mean, rather than what it actually says.I find it fascinating that some very intelligent people are construing this sentence to mean how much weight is required to make the object 50 pounds negative. That is not what the sentence says at all. Whether it is what the original question said, or whether it is what the original question MEANT, we don't know. But it is not what THIS question says. It says we are ADDING 50 lbs of negative buoyancy, which requires 50 lbs of lead.
Go back and read again, you'll find out why.If Johnny only has 3 apples how can you take away 50?

It almost certainly was miswritten or misremembered in the original question. But the answer is simple, and Sparticle, I'm surprised at you! Parse the sentence.
Maybe it would help to use the same language in a more familiar context:Re-read the question.
What amount of lead would be required to add 50 lbs of negative buoyancy to the object?
Meaning that they want the object to be 50 lbs NEGATIVE. If the object is starting off 3 lbs positive to begin with, then you need to add 53 lbs of lead to make the object 50 lbs negative.
Re: Johnny and taking away 50 apples. In the original post it says "Johnny has 3 apples...." It doesn't say that Johnny ONLY has 3 apples. IF he has at least 50, one could properly say he "has 3 apples" (he does) AND one could take 50 apples away from him.
The perfect lawyer answer
If a man states a position and his wife is not around to hear it, is he still wrong?Wow I finally won an argument (I think), wish I could do the same; just once, with my wife...

Maybe it would help to use the same language in a more familiar context:
A regulator costs a total of $200. What amount of dollars would be required to add 50 dollars of cost to the object?
There's no way to correctly interpret that as asking for the amount required to make the total cost of the regulator $50.
Simply, as the question was originally worded, it's not a matter of math or physics, it's a matter of logic and reading comprehension. Which is why it was not likely the question asked on the DM test.
