B

Let the average sales be x.
Total in the year = 12x
January- 0.5x
February - 0.5x
March - 0.5x
April - 0.5x
May- 0.5x
June- 0.8x
July - 0.8x
December - 2.5x

Total- 6.6x
Remaining for August through November = 5.4x
Average =1.35x

Hence during this period the sales was up by 35%

D. 45%

Let avg be 10

Month 1 2 3 4 5 6 7 8 9 10 11 12
Sales 5 5 5 5 5 8 8 ? ? ? ? 25

The known sales are 66/120
Total the unknown are 54/120

$$\frac{54}{120} = \frac{x}{100}$$ = 45%

IMO D

Let the average be A, therefore
Jan to May total = 2.5A
Dec = 2.5 A
June + July = .8A+.8A = 1.6A

Total for eight months = 6.6A
Therefore, sales from August to November = 5.4A (12A-6.6A).

Hence, % = (5.4/12)*100 = 45%

E. 50%

Let the Average Sale be $$100 = \frac{Jan + Feb + ---------------- + Dec}{12}$$
Given, $$Dec$$= $$\frac{Jan + Feb + Mar + April + May}{5}$$= $$50$$
So, $$Jan + Feb + March + April + May = Dec = 250$$
$$\frac{June + July}{2} = 80$$ ---->$$June + July = 160$$
So, we have $$Aug + Sep + oct + Nov = 1200 - (250+250+160) = 540$$
$$% sales = \frac{540}{1200} = 44.16%$$
