@Gupta: Given the balance scale and only the eight coins, with no knowledge
of the values of their weights, here is an algorithm, probably not optimal,
to label each coin x, y, a, or b, with three x's, three y's, one a, and one
b.
1. Weigh the coins pairwise, c1 vs c2, then min(c1,c2) vs
@Gupta: You haven't defined the problem sufficiently.
What type of scale do we have, a balance scale or one that gives a numeric
reading?
Do we know x, y, a, and b, or are you just saying that one set of three
coins weigh the same, another set of three also weigh the same but have
@ Dave sir
the balance considered here is simple balance scale incapable of
giving any numeric reading and the we are unaware of any relationship
between x,y,a,b or any kind denominations prioirity in terms of
weights...
@navin..
3 of them weigh x means 3 of the coins individually weigh x gms,it
@payal:
In this case too i think minimum number of weighing required is 3.
Slightly change in my previous solution. x1+x2+x3 = 3x and y1+y2+y3 = 3y.
