If i take out 3 socks then it may be as follows;
black ---- brown
1 ---- 2
2 ---- 1.
Without this there is no combination. So one matching pair of socks must be. So the answer will be 3.
black ---- brown
1 ---- 2
2 ---- 1.

Hi Geek: The man should have to take out a matching pair.
If he need just a pair of socks, 2 socks itself are enough.
So the answer should be 22.

In starting he take 2 socks =if 1 is black and 1 is brown.
Know he needs 1 socks (black/Brown),
So 2+ 1=3.
The answer is 3.

3 is the right answer. Even if you have all 3 of the same colour, you still have a matching pair :).

Hi, according to me, It sounds impractical because one of the socks is going to be different leg.
