Answer: Blue person gets 4 balls , Green person gets 2 balls , 4 Red persons share one ball.
To find : Number of Members in Each Group
Solution:
Blue Person = B
Green Person = G
Red Persons = 100 - B - G
B Blue Person Get Balls = 4B
G Green people gets Balls = 2G
100 - B - G Red Person gets Balls = (100 - B - G)/4
4B + 2G + (100 - B - G)/4 = 100
=> 16B + 8G + 100 - B - G = 400
=> 15B + 7G = 300
=> 7G = 15(20 - B)
=> G = 0 & 20-B = 0 => B = 20
G = 15 & 20-B = 7 => B = 13
G = 30 & 20 - B = 14 => B = 6
G = 45 & 20 - B = 21 ( not Possible)
