Which type of battery had the highest total sales over the last seven years?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 32AH.
Given that
The total sales over the last seven years of 4 AH battery = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
The total sales over the last seven years of 7 AH battery = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
The total sales over the last seven years of 32 AH battery = 114 + 102 + 72 + 150 + 135 + 165 + 165 = 903
The total sales over the last seven years of 35 AH battery = 102 + 84+ 105 + 90 + 75 + 45 + 100 = 601
The total sales over the last seven years of 55 AH battery = 108 + 126 +135 + 75 + 90 + 120 + 145 = 799
Hence, the highest total sales over the last seven years of 32 AH battery
