Answer:
5120
Step-by-step explanation:
divide the entire group into 10 groups where each group has a man and his wife.

the number of ways selecting 1 person from a group is 2C1 =2 .
So that means the number of ways of selecting 1 person from 9 groups is 2^9=512
number of ways to form the committee is 10*2^9=5120
