Answer:
21%
Step-by-step explanation:
Actually there are three levels of process here.
If 100 calls are made only 70 calls are completed (since 30%not completed)
Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.
28 females and 21 males
Out of 28 females 45% buy something =
Out of 21 males 40% buy something = 
Total percent of calls result in a sale =
