Hey, you have mixed out two questions, and neither of the questions is written completely.
One question seems to be "the mean score ... two students were" and the other one to be "... 800 of which ... would be ".
If you have any doubt in the questions, kindly repost the questions separately and clearly (so that one of us can answer it accordingly).
