Scores in four tests \(= 90, 92, 78, 95\)
Qt A
Avg of five should be \(90\) so the total of scores will be \(450\)
Score needed in fifth tests \(= 450 - (92 + 90 + 78 + 95) = 95\)
Qt B > Qt A
Answer B
Qt A
Avg of five should be \(90\) so the total of scores will be \(450\)
Score needed in fifth tests \(= 450 - (92 + 90 + 78 + 95) = 95\)
Qt B > Qt A
