The riddle is that three pals exit to a restaurant the place their invoice quantities to 25 kilos. In order to separate the invoice, every good friend throws 10 kilos into the pound. When the waiter returns with their change, he retains 2 kilos for himself and returns a pound every to every of the three pals.
Since every particular person obtained 1 pound again, it means they successfully paid 9 kilos every.
This signifies that collectively paid 27 kilos, explains the TikTook consumer. Since 27 kilos plus 2 kilos (the waiter’s) equals 29 kilos, he asks viewers to clarify the place the lacking 1 pound went.

Since being posted on the video-sharing platform in December final 12 months, the brainteaser has collected over 1.6 million views and 1000’s of baffled feedback.
“Too much math for me,” wrote one particular person within the feedback part.
“I don’t get it,” one other confessed.
According to The Mirror, it’s the wording of the brainteaser that makes it so complicated. The riddle is an instance of casual fallacy, which means the error lies within the reasoning.
To make it clearer, assume the overall invoice to be 27 kilos, together with the waiter’s tip. With the waiter’s 2 kilos, the invoice quantities to 27 kilos, and every good friend will get a pound again.
Since 27 kilos added to three kilos equals 30 kilos, the ‘lacking’ pound just isn’t actually lacking in spite of everything.
