I have to admit, I have no idea how you guys solved this... can someone give me a step by step, idiot's guide to solving this problem? I'm more interested in how (mathematically) you guys solved this than the answer.

I'm new here, so this could be (and I probably am) way off base...
I have no idea about the average Grundo weight, but what if you look at the lightest pair (228)...
Assuming the lightest Grundo is only 1 lb., that makes the heaviest Grundo 227 lbs.
Granted, that totally throws off the "average" weight since the 10 weights less 227 range from 1 lb. to 31 lbs.
Is this at all possible? Or is 132 lbs. absolutely the correct answer?

Sorry for being a newb!
Thanks!

Total weight of five grundos (a - heaviest, e - lightest) a+b+c+d+e = sum of all 10 measurements / 4 (every single grundo was weighted exactly 4 times) = 606
a+b - the highest available weight = 258
d+e - the lowest one = 228

c= (a+b+c+d+e) - (a+b) - (d+e) = 606-228-258 = 120

a>b>c => a+b>a+c>b+c, so the SECOND heaviest sum weight is sum of a and c
a=252-c=132

Round 160:
elybelly wrote:
Five Grundos took turns weighing themselves on a scale. However, they weighed each other two at a time, ten times total , so that every possible combination of two grundos was weighed. The scale had the following readouts for the pairs: 236 pounds, 244 pounds, 228 pounds, 250 pounds, 258 pounds, 230 pounds, 246 pounds, 238 pounds, 242 pounds, and 252 pounds.

How heavy was the heaviest Grundo?

This is a variant of the classic "haybales" or "pumpkins" problem.

. . . . .Ask Dr. Math: Weighing Bales of Hay (1997)

. . . . .Ask Dr. Math: Weighing Bales of Hay (1996)

Note that the weights in this puzzler, in order, are:

. . . . .228, 230, 236, 238, 242, 244, 246, 250, 252, 258

Then follow the methodology of the above (or other) examples.

Not to be too ignorant, but...
In your example of a + c where a=252 and c=132....
Does that make a=252 the heaviest weight?
Which isn't really possible since the lowest weight of two Grundo's is only 228??

You're counting a+c as a. a would actually be 252 - 132, or 120.

what was said was a= 252 - (c) = 132 where c=120

^This is what I'm correcting in my previous post. a alone is not 252, obviously.
