Iq 130+ simple but confusing brain teaser.

AI Thread Summary
In this discussion, a jewelry shop owner faces a dilemma when a customer attempts to buy a $70 ring using a fake $100 voucher. Lacking cash, the jeweler borrows $100 from a neighboring pastry shop owner, gives the customer the ring and $30 in change, and later learns the voucher is worthless. The key points of contention revolve around calculating the total loss incurred by the jeweler. Many participants argue that the loss totals $100, which includes the $70 value of the ring and the $30 given as change. Others mistakenly calculate the loss as $130 or $200, failing to recognize that the $100 returned to the baker was merely a refund of borrowed money, not an additional loss. The discussion highlights confusion over the definitions of gross versus net loss, with some emphasizing the importance of understanding the intrinsic value of the ring and potential profits.

ok,
you start off with $70 (ring)
+$100(banker)= $170
-$70(ring)=$100
-$30(change)=$70
-$100(banker)= -30$
but he started with a ring so total losses = ring+$30

how is this thread longer than some of the advanced physics threads??

yes. we must somehow revive Gauss, for only he can settle this :rolleyes:. seriously guys. let's give it a rest.

(I still stand by my "OP didn't specify if by 'loss' he meant net loss or gross loss" opinion *muahaha*)
