“When I was six, my sister was half my age. Now I’m 70, how old is my sister?”

The answer to this question is of course 67. Under pressure though, it is very easy to fall into the trap and answer 35 instead. Despite this though, most people manage to work it out in the end.

Welsh tradesman Kearon, well and truly fell into this trap. He was asked this question by one of his fellow workmates. He responded confidently stating: “35 innit.”

This answer was, of course, met by a fit of laughter from his surrounding workmates, much to the confusion of Kearon. He then asked his workmates to explain it again, slowly. However, Kearon still doesn’t quite grasp the question and replies with: “it’s still half your f*cking age isn’t it.”

His fellow workmates, of course, loved this response. This guy’s face says it all really.

After these first failed attempts, the workmates were enjoying themselves and asked Kearon the question again. There was silence from Kearon though whilst the worker behind the camera was laughing away. To this, he responded: “I don’t know why you’re laughing as if it’s a simple f*cking question.”

To which his workmate responded: “it f*cking is!”

After clarifying there was no trick involved in the question, Kearon is asked the question again. Defensively, Kearon argues once again that the answer is “f*cking 35.”

As the worker is getting nowhere, the workmate decides to break it down for him further. He explains that when he was six, his sister was three years old. It is at this point, that Kearon appears to grasp the answer, despite being distracted by the mocking voices of his workers around him claiming in a high pitched voice, “it’s still 35.”

However, Kearon defends himself stating “no I’m changing my maths here now.”

“I’ve got this now, I’ve got this.”

Unfortunately, though, Kearon hasn’t got it, and he is still unable to reach the right answer. Instead, this time, he answers 38. Then, he gives a succession of wrong answers including 32 before going back to his original answer of 35.

It is at this point, that Kearon’s workmate decides to provide him with the answer. He exclaims, “she’s only three years younger than me you daft c*nt.”

However, despite this, he still struggles to figure out the maths as his workmates begin to laugh again. Finally though, after three minutes, he finally gets the correct answer of 67.
