63) How many squares are present on the chess board?
a) 64
b) 204
c) 360
d) 100

• 204.
  Generally for a n x n board the normal formulae is a sigma of n^2. i.e (1^2 +2^2+3^2....n^2). so for a normal chess board, we have 1^2 +2^2+3^2+4^2 +5^2+6^2+7^2 +8^2.
  =1+4+9+16+25+36+49+64= 204
  
  So we have 204 squares present in a normal chessboard.
