Correct Answer - Option 4 : 2007
Formula used:
Percentage of Pepsi sold = (Number of Pepsi/Total number of drinks) × 100
Calculation:
Percentage of Pepsi sold in 2004 = (96/525) × 100 = 18.28%
Percentage of Pepsi sold in 2005 = (105/510) × 100 = 20.58%
Percentage of Pepsi sold in 2006 = (90/465) × 100 = 19.35%
Percentage of Pepsi sold in 2007 = (105/495) × 100 = 21.21%
∴ The percentage of Pepsi sold to the total number of drinks sold was maximum in the 2007.
