A Simple maths challenge to solve problem using just one line leaves people baffled.
A video showing three engineers struggle to solve a puzzle using a single line has gone viral, racking up nearly 40 million views on TikTok.
TikTok user shared a clip, handing the problem to three friends who work as engineers and setting them the task of solving it in under three minutes.
The piece of paper shows the number 100 stacked on top of another 100, and she says: "If you can turn this into 200 with one line, I'll give you whatever you want."
The friends try turning the paper round to look at the puzzle from different perspectives, and even accuse her of writing the question wrong,
but ultimately appear to be unable to solve the sum using a single line as they demand more time.
Try solving by yourself and give your answer in the comment section.
The tik tok puzzle video has gained more than 17,000 comments as thousands of people were left stumped,
while a worrying number also failed to grasp the concept of only using one line.
Thankfully, with seconds to spare, one of the engineers finds the answer she was hoping for by removing the mathematical logic altogether.
What do you think, are you satisfied with the answer, comment below.
