Answer:
64
Step-by-step explanation:
we have given that mean of 9 students is 84
so total score of 9 students = mean×9
=84×9=756
and we have given mean score of exam is 82 and there is total 10 students so the total score of 10 students =10×82
=820
so the unreadable score = score of 10 students -score of 9 students =820-756=64
