Dear Student

Number of ways of selecting 2 men out of 7 men for a game = 7C2      

Wives of chosen men cannot be selected so no. of  ways of selecting women = 5C2        

                                                                                                            

For each selection of 2 men and  women 2 matches can be played

          Total matches = 7C2 x 5C2 x 2 = 420
