What Does She Need To Score On The Fifth Teat To Get Exactly A Mean Of 90 class=

I think I can bravely ignore the Freudian slip and solve this one.

-- If the mean of 5 tests is 90, then all 5 scores add up to (5 x 90) = 450

-- The sum of her first 4 scores is (95+ 90 + 85 + 95) = 365

-- If she has one more test to average 90, then she needs
to score (450 - 365) = 85 on it.

That looks like choice 'G '.
