The number of matches played in each Pool = (4 × 3)/(2 × 1) = 6 So the total number of Pool matches = 4 × 6 = 24 The winners and second placed teams play a further 4 matches. Then there are 2 semifinals and 1 final So the total number of matches = 24 + 4 + 2 + 1 = 31

then there are four battles for the case 2 (after pool matches are comleted) = 4 then case 3 (winners of case 2 to fight for semifinals) = 2 case 4 (battle for finals) = 1 Hence it is 24+4+2+1 = 31
