  1. The answer is A). Because in box 1 objects are in pair form So if I pick 20 pairs of socks,then I have got all the socks.Now if I pick 3 gloves from box 2 then there must be 2 gloves of same colour i.e. red or black.So in any case I have got a pair of socks and gloves with same colour.

  2. I think that none of the above option is correct. Below I have explained why I think so-

    Option A-it is an incorrect option since we may choose 20 red socks from Box-1 and 3 black hand gloves from Box-2

    Option B- it is also an incorrect option since we may have chosen 3 red socks from Box-1 and 20 black hand gloves from Box-2

    Option C- this is not correct because we may have chosen 20 red socks and 1 black sock from Box-1 and 3 black hand gloves from Box-2

    Option D- it is also an incorrect option since we may have chosen 3 red socks from Box-1 and 20 black hand gloves and 1 red hand glove from Box-2

    In all the above cases we do not get a pair of socks and a pair of hand gloves of the same colour. So each of the given options are incorrect

    By the way, one of the correct answers may be, choosing 3 socks from Box-1 (so that we get one pair of socks of one colour), and 22 hand gloves from Box-2 ( so that we get pair of hand gloves of each colour)
