The total sales of all the seven years is the maximum for which battery ?


A) 4AH

B) 7AH

C) 32AH

D) 35AH

E) 55AH

Answer:

Option C

Explanation:

The total sales (in thousands) of all the seven years for various batteries
are : a t.
For 4AH    = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676

For 7AH    = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694

For 32AH  = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901

For 35 AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601

For 55 AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.

Clearly, sales are maximum in case of 32AH batteries.
