GoogleStore.orgPuzzle -If you are good in maths
[Caution] Enter Only if you are good in Maths!
[Puzzle]: Breaks apart a 40KG stone into 4 pieces in such a way that using those 4 parts anyone can weight 1KG to 40KG each weights.
Let me describe a little bit more....
Suppose the 4 parts are: A, B, C and D
So,
A+B-C=1KG
B+D-C=2KG
A+D-B=3KG
...............
...............
A+B+C+D=40KG
So, what are the weights of those 4 pieces...??
Note: All pieces are rounded-off in weights, like, each parts are in complete KGs and note in Grams...
Hope you are good enough in maths....huh!
I bet only a mastermind can solve this........

Everytime we gotta use 4 stones only or we can use fewer also?
Edit: nevermind, figured it out.
1,3,9,27.

I dont think the question is written out very well...
Unless I just simply don't understand it.
"Breaks apart a 40KG stone into 4 pieces in such a way that using those 4 parts anyone can weight 1KG to 40KG each weights."
Well, that's not right for a start. If one of those 4 pieces weigh 40KG, then where are the other 3? lol
Can't A B C and D all be 10KG's making 40KG ?
I don't know, I just don't get it.

Its common sense that none of them can be 40kg or anything over 37kg also.
You gotta make 4 such weights so that if you add or subtract any weight then you can get any weight from 1-40kg. Try with the answer which i supplied above.

All of them have to be integer weights. Also, if you disregard this rule, you cannot get 2KG out of these weights ( and many more. I just checked for 2).

A = 6.285 (i.e) A = 44/7
B = 10.571
c = 15.857
D = 7.285 (i.e) D = 51/7
EDIT:
Fully solved in paper
So, what are the weights of those 4 pieces...??
Note: All pieces are rounded-off in weights, like, each parts are in complete KGs and note in Grams...
B = 10.571 ~~ 11
c = 15.857 ~~ 16
D = 7.285 ~~ 7
may be i am wrong in rounding off
Note:
Even i checked in calculator, value i correct, so round off may wrong
For checking in calculator:
take 4 x 4 linear equation
(equation 1) => 1A +1B -1C +0D = 1
(equation 2) => 0A +1B -1C +1D = 2
(equation 3) => 1A -1B +0C +1D= 3
(equation 4) => 1A +1B +1C +1D = 40Skipp the Adfly Adfocus LinksBucks by one click(No Ads, No pop up's)

TvBlog.ws TeenBabe.in SexyBitch.in BabeLips.in CuteBabe.in Sweetie.co.inA+B+C+D=40
A+D-B=3
B+D-C=2
A+B-C=1
So,
A+C-2B=1
D=1+A
B=2A-2
C=B+D-2=3A-3
B+C+D=6A-4
7A-4=40
.. 7A=44
Didn't do any proper math for last 10 yearsBut it doesn't go any other way for me
If Nitish is correct. Then
A=1
B=6
C=9
D=27
Then, A+B-C=-2 (That is wrong!)
