An interesting puzzle is gaining popularity online, but not everyone can do it. Try to determine the weight of a white ball.
Puzzles test critical thinking and improve problem-solving skills. These tasks have the potential to increase intelligence, experts say.
Numerous studies have shown that daily intellectual training helps to keep the brain in good shape and can eventually prevent the risk of age-related neurological problems, including dementia.
In the image, we see a balance of red, white, and green balls. The green one weighs 30 units. According to surveys, only the smartest and most attentive were able to calculate the weight of the white ball in 11 seconds.

This puzzle will test your analytical and logical thinking skills.
Explanation
In the image, the value of the green ball is 30.
All you need to do is write an equation.
If we assume that the value of the red ball is x and the value of the white ball is y, we get
x + 2y = 3x + 30
Or
10+2y = 30+30
2y = 50
y= 25
So, the weight of the white ball is 25.
