Hello Marsha;
My 12 year old daughter got her version of the bales of hay problem and it is driving us nuts. I checked solutions on the internet, but the explanations were not enough.. Although I was able to derive the 5 numbers I could not explain how I got it. Any words of wisdom or assistance you could give would be appreciated.
Here is the version my Daughter got:
suppose five bales of hay are weighed two at a time in all possible ways. The weights in lbs are 110, 112, 113,114,115, 116,117,118,120 and 121. How much does each bale weigh?
I'm a card carrying engineer for HP's MPE and UNIX operating systems, but I never had this problem in public school or during college.
Any help would be appreciated from this frustrated father.
Cheers; Ike Leong
