Sorry, if this is a trivial question. But I feel really confused when I ask people, their answers are different to my answer. So I want to ascertain what exactly is answered to this question.
For example: We have some kind of call (bank customer's call, mobile customer's call, Data base calls) which we have to make. When I ask a question to one guy
What calls you are making?
Should the answer be in number of call or which call?
