Question

1. This hanger is in balance. There are two labeled weights of 8 grams and 28 grams. The four circles each have the same weight. What is the weight of each circle, in grams? A. 3 B. 7C. 5D. 20/12

Answer 1

Given data:

The left side weight is L=28 grams.

The given right side side is r= 8 gram.

The expression for the balance equation is,

$\begin{gathered} L=r+4x \\ 28=8+4x \\ 20=4x \\ x=5\text{ grams} \end{gathered}$

Thus, the option (C) is correct.
