Answer:
the new ratio of white, red and blue balls is 6:2:1
Step-by-step explanation:
The computation of the new ratio is shown below:
If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls
Now if 10 white and 10 blue balls would be eliminated
So there is 30 white, 10 red, 5 blue bals
Also
30 = 5 × 6
And,
10 = 5 × 2
so the new ratio of white, red and blue balls is 6:2:1
