Question

Adam tried to compute the average of his 7 test scores. He mistakenly divided the correct sum of all of his test scores by 6, which yielded 84. What is Adam's correct average test score?

Answer 1

Adam's correct average test score is `72`.

As sum of scores is `504` in `7` test scores,

Adam's correct average test score is `504/7=72`.
