Question

कारण (2) कोविड-19 समस्या और समाधान​

Answer 1

You might ask me, “Do you know his number?” because maybe I know the yoga instructor's number, but maybe I don't. You're not sure. You're not certain, so you could ask me, “Do you know his number?” I'll either say, “Yes, I have his number. Here it is.” Or, I'll say, “No sorry, I can ask him about it.”
