Expected minimum rating = 8

Deviation from the expected minimum rating = (-1 + 0 + 0 - 1 + 1 + 2 - 2 - 2 + 0 - 1)/10 = -4/10 = -0.4

Current rating is 0.4 less than 8.

Percentage = (0.4/8)*100 = 5%

Great Question.
Here is what i did in this Question-->
Desired Mean => ≥8
Current mean => 7.6
Shortfall => 0.4
So the Question is really asking us "0.4 is what percent of 8"
And 0.4 is 5 percent of 8.

Hence B

(A) 4%
(B) 5%
(C) 8%
(D) 10%
(E) 12%


Total score of June is 76

She wants total score of 80

So, She fell short of 4/80*100 = 5%

Hence, answer will be (B) 5%

+1 for B. The trick here is to take differences over 8 and sum them up. Now once you get the net differential , calculate the %
