Answer:
- 36
Step-by-step explanation:
The ratio is given:
- b : r : y = 9 : 6 : 3
Let each equal part be x, then we have:
- b - r = 6
- 9x - 6x = 6
- 3x = 6
- x = 2
Total number of counters:
- 2(9 + 6 + 3) = 2(18) = 36
Step-by-step explanation:
Let,
Blue counter = 9x
Red counter = 6x
Yellow counter = 3x
Given,
9x = 6x + 6
9x - 6x = 6
3x = 6
x = 6/3
x = 2
Now,
Total number of counter = 2(9) + 2(6) + 2(3)
=> 18 + 12 + 6
=> 36
