A lady has fine gloves and hats in her closet- 18 blue- 32 red and 25 yellow. The lights are out and it is totally dark inspite of the darkness. She can make out the difference between a hat and a glove. She takes out an item out of the closet only if she is sure that if it is a glove. How many gloves must she take out to make sure she has a pair of each colour?
a) 50
b) 8
c) 60
d) 42

• as lights off
  first we remove 32 red
  then 24 yellow
  then 1 yellow 1 blue
  and then 2 blue
  thus we get pair for all colors
  so total = 60
