CAN YOU ANSWER THIS QUESTION? (page 5)

This is the way I would figure 99% of 100lbs is 99lbs to start then you take 98% of 99lbs and you get 97.02 lbs.

well, the way I figured it, I came out with 98.98 as the answer, it's algebra, isn't it? I used to be good at algebra, but that was decades ago.

50 LBS!!!

Cos you ate meat, gravy,peas,with them Then had a whacking great slice of Cake & Ice-cream to top it off

ROFL!!!!

I can just HEAR Mouthy saying this with her delightful British accent.....the "whacking great slice of cake".....is TOO precious!!!!

PS----do we get to hear the answer from Terry???

My guess would be 1 pound. Assuming that the water weight is not relavant.

I got kicked out of the WT cos I cant do my arithmetic, if I couldnt work out 1914( they told us how to do it) How can I work out your question I dont know

The only way I comprehend things like this is to create a little model for myself and then hack through it. Then, I use the model to attack the larger problem.

Once you do it that way it is more like washing a sinkfull of dishes one dish at a time. The whole mess is daunting, but, eventually it gets done.

what kind of potatoes are they?...how many potatoes are in a pound?

What method is used to measure the 1% reduction in water content?

Ahhh, you see this is exactly how I get hung up on math problems. I automatically get sidetracked on the non-essential details!

Think of it this way: You have 100 of anything and the total group weighs 100 lbs. It is easy to see that only one of them would weight 1/100th of the total.

Each time you figure the problem you start afresh with the total vis a vis the component proportion of the total.

What these things may be is irrelevant and how you weigh them is irrelevent.

It is the process which is key.

..99lbs..The potatoes were originally 99% water and wieghed 100lbs..Dropping 1 percentage point to 98%,would be the loss of 1lb...OUTLAW

This is the "intuitive" answer and it is WRONG!

The reason I posed the problem is to (later) use it as a metaphor for how we go wrong reasoning "obvious" things "intuitively"

Try again! You are waaaaay off.

Terry

100Lbs / 99% water so, final weigh if moisture is reduced to 98%?:
X=((100 Lbs) * 98%) / 99% = 98.99 Lbs
Somehow I don't expect this to be about the math but syntax.

Thank you for a logical presentation of a WRONG answer!

Your process is impeccable. However, it is the wrong way about it.

Try again.
