Answer :

6 balls , 2 red , 2 blue , and 2 green .

Solution :

Here , the main trick is to see the statement carefully .

I have a bag , with some balls with it .

All but four are blue , all but four are green , and all but four are red .

Suppose that there are x balls in the bag .

Number Of Blue Balls :

=> x - 4

Number Of Red Balls :

=> x - 4

Number Of Green Balls :

=> x - 4

Total Number Of Balls

=> 3 ( x - 4 )

But , the total number of balls is x .

=> 3 ( x - 4 ) = x

=> 3x - 12 = x

=> 2x = 12

=> x = 6

Number Of Blue Balls :

=> x - 4 = 2

Number Of Red Balls :

=> x - 4 = 2

Number Of Green Balls :

=> x - 4 = 2
