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

Answer:

  • 36

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
