(Image credit: https://twitter.com/Rainmaker1973) Here’s a new challenge for you. The challenge here is to determine the actual height of a glass from the total height of four and two glasses stacked on top of each other. In the image shared on X (formerly Twitter) by Massimo (@Rainmaker1973), there are two sizes: one is 34 cm, which is the height of four glasses stacked on top of each other, the second is 19 cm. the height of two cups stacked on top of each other. The question is to find the height of a single cup. Solving brain puzzles brings many benefits, improving cognitive abilities such as problem solving skills, critical thinking and multi-dimensional thinking. It stimulates the brain, improving memory retention and cognitive flexibility. Engaging in tough questions also enhances creativity because it encourages new approaches to problem solving. Furthermore, solving tough questions brings a sense of accomplishment and satisfaction, boosting confidence and self-esteem. It promotes mental agility and enhances concentration, which in turn can improve performance in daily tasks and professional endeavors. Ultimately, regularly engaging in brain teasers will contribute to overall brain health, promoting lifelong learning and mental health.
answer
Let the height of a cup be x. Let y be the height we can see after we stack the cups on top of each other. Since the glasses are of equal height, the y-factor will be the same for all the glasses. According to details available in the question:x+ 4y = 34x+ y = 19x= 19- y19-y + 4y = 34 solve for y:3y = 34-19 = 15y = 5
Now that we have determined y, let’s put its value into the equation: x + 5 = 19x = 19-5 = 14So the glass is 14 cm high
However, some X users reported that the height of the glasses is 15 cm. What do you think the correct answer is?
