The shopkeeper lose $100 (Answer)

Solution 1:

The first thing is that the second shopkeeper has no role in this puzzle, it’s just there to create confusion. Because whatever he (the 1st shopkeeper) trade with the 2nd shopkeeper, he got back.

Now just think like that, A lady enter the shop with no value (fake bill = zero value) and when she comes out from the shop she has goods worth $20 and $80 in cash, total = $100 worth

So, again

Lady Enter = 0 value

Lady Out = $100 worth ($20 goods + $80 cash)

Now just think about it, somebody loses money in the shop and who’s that guy?

Of course, the shopkeeper

And how much money did he lose?

The $ 100 bill.

Got it? Simple right? and for those who didn’t understand the simple one, here is the second solution.

Solution 2:

Loss of 1st shopkeeper = (Profit of the lady + Profit of the 2nd shopkeeper)

Profit of the lady = $20 (for goods) + $80 (for the change) = $100

Profit of the second shopkeeper = $0 (as he got his money back)

So the loss of the shopkeeper is = 100 + 0 = $100
