All the items are gloves then according to my opinion 14 blue- 20 red and 18 yellow are gloves, then atleast 40 gloves must be taken out to make sure she has a pair of each colour.
20+18+2=40

14 blue 20 red and 18 yellow
to make sure that she has a pair of each colour leave the minimum value which is blue and add 20 and 18 = 20+18 =38
and 2 from blue gives = 38+2=40

so atleast 40 gloves must be taken.

in the worst case say the lady takes out all the gloves of the same color, for the number to be minimum say she takes out all 14 blue. now on the next 18 draws she takes out all the yellow glove and now on the next two draws she will have a pair of each for sure...
so in order for her to have pair of each glove she has to take out at least 14+18+2=34 gloves....

they said ATLEAST. the answer is 4.
wen she took out three gloves, n still has no pair of same color, den next glove she will take out, must b one of those 3 colors and ultimately a pair will b made. so SOLUTION Is 4 gloves
.

14LB+(20*2 red)+(18*2 yellow)+ 1 RB = 91

If we assume that the lady takes out gloves of same color, taking the minimum number to be of blue, the lady takes out 14 gloves all of blue color then she takes out all of yellow colors i.e. 14+18=32. Now she already has pair of yellow and blue gloves, so in the next turn, she will take out red gloves only i.e. 32+2=34. So answer=34
