Understanding the Problem
To find the number of green balls in the bag, we need to analyze the information given in the problem statement. We have three types of balls: green, twin, and blue.
Relationship Between Balls
- The ratio of the balls is given as one-third and two-sevenths for green and blue respectively.
- The number of green balls is stated to be 8 less than twice the number of blue balls.
Setting Up Variables
- Let the number of blue balls be denoted as B.
- The number of green balls will then be represented as 2B - 8.
Using Ratios
- From the problem, we can assume:
- Green balls = (1/3) * Total balls
- Blue balls = (2/7) * Total balls
Assuming the total number of balls is T, we have:
- Green balls = T/3
- Blue balls = 2T/7
Equating the Number of Green Balls
Since we have two expressions for the number of green balls, we can equate them:
- T/3 = 2B - 8
Finding Total Balls
To solve for T, we replace B with T/7 (from the blue ball ratio):
- T/3 = 2(T/7) - 8
Now, solve for T:
1. Multiply through by 21 (LCM of 3 and 7) to eliminate the fractions.
2. Simplify to find the value of T.
3. Substitute back to find B and then calculate green balls.
Final Calculation
After solving, you will find the number of green balls using the equation:
- Green balls = 2B - 8
This systematic approach leads you to the desired number of green balls in the bag.
