Stupid Seller??? Two men A and B go to the market to sell eggs. Each one has 30 eggs. A sells 2 for one unit(insert your own monetary unit) and B sells 3 for one unit. Just before they start to sell, A gets an urgent call from his home, he requests B to sell his stuff and goes home. B, the wise man, mixes both the eggs and sells 5 for 2 units. When finally he counts the money, he gets 1 unit short(60 = 12*5 and 12*2 = 24units) Can we suggest him the trick so that he won't repeat the mistake again?
