A lady has fine gloves and hats of different colours in her closet 18 blue, 32 red and 25 yellow. The lights are out and it is totally dark. In spite of the darkness, she can make out the difference between a hat and a glove. She takes an item out of the closet only if she is sure that it is a glove. How many gloves must she take out to make sure that she has a pair of each colour?

Solution:
Suppose the lady first picks :
32 Red gloves and then 24 Yellow gloves.
The next pair she picks will be one Yellow and One Blue which does not make a pair.
= 1 yellow + 1 blue
Again she will have to pick two more.
The next two will be blue gloves given that he has already taken out yellow and red out and one blue.
So she will make a total of :
32red + 24 Yellow + 1 yellow + 1 blue + 2 blue = 60
She has to pick 60 gloves.
