Maths Puzzle
there are 16 balls in a bag 8 red 4 green 4 blue.find least no. of balls to be taken out such that we have atleast one ball of each color
Read Solution (Total 4)
-
- 13
Since we always had to consider all the possibilities in this type of question. So assume we had drawn 8 balls (possibility that all are red) so we need to draw more balls.
Again we draw 4 more balls say all are green this time. Total till now = 8+4=12
Now we only have to draw one ball so that there is atleast one ball of same color.
Thus least no. of balls=8+4+1=13 - 10 years agoHelpfull: Yes(3) No(0)
