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 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 it is a glove. How many gloves must she take out to make sure that she has a pair of each colour?

- There can be lots of logic for this, but approach the simplest one so that we approach to one of the solutions. Suppose the lady first picks 32 Red gloves, and then 24 Yellow gloves. The next pair she pics will be one Yellow and One Blue which does not make a pair. The next two will be blue gloves. So she make a total of 32+24+1+1+2 = 60 picks.

- in first lady takes 32 gloves r red in color
she go for next pickup that may be yellow or blue
we assume is it yellow
after then she pickups 24 yellow gloves
only one yellow be there probability for getting blue also
so 1+1 yellow +blue
so now there is no yellow and red gloves
so she pickup 2 gloves which must be in blue
32+24+2+2=60
ans :60........... - 10 years agoHelpfull: Yes(4) No(2)
- Here there is no logic just follows following formula.
Add max two numebers
32+25=57 now add 1,2 or 3 acording to given in options..
So answer from given options is 57+3=70. - 13 years agoHelpfull: Yes(3) No(38)
- we take maximum number in gloves colors 32 + 25 + 2 = 59.

- shortcut formula
max+middle+2
32+25+2=59 - 9 years agoHelpfull: Yes(3) No(0)

- for red -1 (red) + 25(yellow) + 18(blue) + 1 red = 45,,,,,,now red is 30 only
for yellow - 1 (yellow) + 30(red) + 18 (blue) + 1 (yellow) = 50,,,now yellow is 23
for blue - 1 (blue) + 30(red) +23 (yellow) + 1 (blue) =55
total=45+50+55=150
- 9 years agoHelpfull: Yes(0) No(1)
- I think it's 18+25+2=45 picks
