Only people with a super high IQ can solve this mind-bending brainteaser in just 15 seconds or less – and almost no one can solve the challenging maths problem
A new mathematical brainteaser has been dubbed “frustrating” after it left even the brightest minds stumped.
Shared by the account @BrainyBitsHub on X (formerly Twitter), this new puzzle has left people in a tailspin. This intriguing brainteaser requires you to use your problem-solving skills to find the solution. But almost no one has been able to solve the challenging maths problem, leaving people feeling frustrated.
This new brainteaser is made up of three mathematical problems, which are written on one sheet of paper. The problem reads: “4 + 3 = 21, 2 + 5 = 35, 7 + 4 = ??”. For most people, the puzzle seems somewhat illogical – which makes finding the solution seem almost impossible, especially in under 15 seconds.
The brainteaser has got over 6,000 views on X and more than 300 comments, with people unsure how to go about finding the solution. Lots of users were quick to comment on the problem, one said: “I’m convinced this is some sort of trick! Maths was never my strong suit!” Another shared the same sentiment and said: “If only my teachers could see me now, struggling with what looks like a simple equation!”
While one confident user revealed that they had found the solution, writing: “I’ve cracked it! The answer is definitely 65!”. While another user proclaimed: “I feel like I’m losing my mind trying to figure this out!”
These kinds of brainteasers are a great tool for sharpening your cognitive skills. Solving puzzles like this one can help to boost your problem-solving abilities and improve your memory, because they encourage you to look at things differently to how you usually would do, and they make you approach problems from different angles.
