Very nice indeed, took me 15 minutes.
Since the answer revealed, how about the algebraic way ?
Some people never able to solve it, probably they are using algebra/formula/whatever instead of basic arithmetic ?
6x + 3y + 0.10z = 100 = x + y + z
Yes, I think its associative algebra (whatever that is), see R modules in that Wikipedia.
Assuming we know z. Is it possible to get x and y ? I'm really no idea about this.
x + y + 70 = 6x + 3y + 70 = 100
-------------------------------------------------
Since the question solved before 2nd page lets not waste it. Another question
No google, it defeat the purpose.
Question:
There are 8 ball, equal size and everything except 1, its weight screwed, you are given a balancer/scale and only 3 times balancing act, determine
which ball have wrong weight and is it heavier or lighter than others.
IMHO this one pretty easy compared to the 1 29 70 question above.
