In your bedroom, you have a drawer with 3 yellow, 17 purple, 18 brown, 10 white, 2 green, 5 blue, 11 grey, and 20 orange socks.

It is dark in your bedroom, so you cannot distinguish between the colors of the socks.

So, The Question is How many socks do you need to take out of the drawer to be sure that you have at least three pairs of socks of the same color?

Can anyone answer for this?

Hello all please read the question clearly. It says here he need to take out "1 matching pairs" i.e. either two black or two brown so for doing this he must do 3 attempts because in 2 attempts he might get 1 black and 1 brown which is not matching pair but in 3rd one he sure get a black or brown so therefore he obviously get a matching pair.

And it's also possible that 3 of them might black or brown so ultimately he get 2 (one pair of black or brown) from minimum of 3 from here. So 3 is the "must" no. of socks he need to take out. So answer is 3.

The possible cases are :-

(1) All the 3 can be of same colour.
(2) 1st may be black, 2nd may be brown & 3rd may be brown.
(3) 1st may be brown, 2nd may be black & 3rd may be black.
(4) 1st may be brown, 2nd may be black & 3rd may be again brown and vice versa.

You can easily observe that in any expected case we can have at least one pair.

Obviously the answer is 3 because getting a pair of socks is only the concern. It may be of any colour. There are only certain possibilities which are mentined which will definitely let you to understand that in each case you will get at least one pair of socks of any of two colour.

3 is the answer.

The possibilities are: Black black brown, black black black, black brown brown, or brown brown brown.

Question is, how many socks you have to take, so that you have at least one pair of socks, of same color.

Answer is obviously 3, when you take more than 20, you will be having at least more than 5 pairs of socks, of same color.

Guys here the person just needs one pair of socks to wear either Black or Brown, So if he takes out 3 socks them he may get all 3 black or Brown or 1 Black and 2 Brown socks or 2 Black and 1 Brown socks so any one will make a pair so the problem will be solved. So answer is Three. If still not understood please try once with 20 pair of socks thank You.

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.

For people who are saying that answer should be 22.

He need to find a matching pair. Not the matching pair of particular color. So taking any 3 he will ensure that he has found 1 pair.

Hope you get my point. :).

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

There are possibilities that all the three socks of same colour. So answer should be 22.
