2. 

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

[A]. 4AH
[B]. 7AH
[C]. 32AH
[D]. 35AH

Answer: Option C

Explanation:

The total sales (in thousands) of all the seven years for various batteries are:

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

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

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

For 30 AH battery, the sales figure crossed 100 for seven times (i.e. 114, 102, 150, 135, 165, 160) which is more than others. Therefore, 32AH is the obvious answer.
