Answer:
8/3
Explanation:
This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.
We have to determine,
What is the weight of each circle?
According to the question,
Let the weight of each circle be x.
This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.
The hanger is in the balanced state then the sum of all weight of the left-hand side is equal to the sum of all weight of the right-hand side.
Left hand side weight = x+ x + x+ 4 = 3x+4
Right hand side weight = 12
Then,
The hanger is in a balanced state, the weight of each circle is given by,
The weight of the left-hand side = the weight of the right-hand side
The value of x is 8/3.
Hence, The weight of each circle is 8/3.
