You have two sets of five coins. Each set has four real 30g coins and one 31g fake coin. It is easy to find the fake coins using a balance scale a total of four times, two weighings for each set.

Can you find a strategy which uses only three weighings?

If ABC = abc, then next weighing should be D Vs d and following should be E Vs e.  Whats your point??  Sorry, dont I dont get it.
