Correct Answer: 1170

Explanation:

Possibilities     Bowlers      Batsmen         Number of ways


 


                         6               9


 


         1              4                7               ( 6 C 4 * 9 C 7 )


 


         2              5                6               6 C 5 * 9 C 6
