Can't Understand this Question

I am having trouble understanding this question. Sorry the pic is not quite clear, it's a snapshot from the PC. This question was asked previous year by a company which came to our college for recruitment.

The input example given are more like the multiple of 5. But I think there is more the question I am missing.
