Knowing can be roughly sub-divided as knowing how to and knowing that. If the question is about knowing how to, then the normal 'rules' apply when deciding on the appropriate tense.

Do you know how to make eba? (present tense)

When you started school did you know how to tie your shoelaces? (past tense)

When knowing means knowing that, then the past tense is used for knowledge that existed in the past:

Did you know that she was married when you asked her to dance?

You can use the present tense for present knowledge:

Do you know that the meeting has been cancelled?

However, it is also very common to use the past tense idiomatically to refer to present knowledge. So there is no problem asking:

Did you know that the meeting has been cancelled?

The past tense is often used when the questioner expects that the listener does not in fact know. For example, see these three questions of "Did you know that ...":

Did you know that he's Saraki's son?

Did you know that the iPhone 6 is a collector's item?

Did You Know That Earth Is Getting Lighter Every Day?

or "...asked her for dance"?

Instead of saying "...asked her for dance" you should say "...asked her for a dance"

However,

"...asked her to dance" is more suitable.

Nice! It's basically the problem of tenses.Nigerians and other peoples who use the English Language as their second language care less about their use of tenses, concord, numbers, person etc.
