Step-by-step explanation:
Let x be the constant of proportionality and let the balls be 3x, 4x, 5x, and 6x...
total balls= 3600
3x+4x+5x+6x=3600
18x=3600
x=200
No. of Red Balls= 3x= 600
No. of Blue Balls= 4x= 800
No. of Green Balls= 5x= 1000
No. of Black Balls= 6x= 1200
Percentage of Red Balls= 600/3600*100=16.6%
Percentage of Blue Balls= 800/3600*100=22.2%
Percentage of Green Balls= 1000/3600*100=27.7%
Percentage of Black Balls= 1200/3600*100=33.3%
