  1. Sir, How answer will be 338350… Suppose we consider a square consist of 3 horizontal and 3 vertical line then clearly no. Of square will be 5…i.e 1sq+2sq=5….In your question square is consist of ? horizontal and ? vertical line so answer should be…1sq+……….99sq=328350

  2. Sir in the given 100 by 100 grid the 1,2,3……100 are the notation of lines…in which only 99 columns and 99 rows……
    Ex.. For making a 3 by 3 square we need 4 vertical and 4 horizontal line……

    We get 328350…if I am wrong…than plz explain
