A company's annual budget is represented by two pie charts for Year 1 and Year 2. If the total budget increased by 10% from Year 1 to Year 2, which department experienced the largest absolute increase in budget allocation? Year 1 Budget Allocation: Research (30%), Marketing (25%), Operations (35%), Admin (10%) Year 2 Budget Allocation: Research (25%), Marketing (30%), Operations (30%), Admin (15%)
✓ Correct Answer: Option B
Let B1 be Year 1 total budget. B2 = 1.1 * B1. Research: Y1=0.3B1, Y2=0.25*1.1B1=0.275B1 (Decrease). Marketing: Y1=0.25B1, Y2=0.3*1.1B1=0.33B1 (Increase of 0.08B1). Operations: Y1=0.35B1, Y2=0.3*1.1B1=0.33B1 (Decrease). Admin: Y1=0.1B1, Y2=0.15*1.1B1=0.165B1 (Increase of 0.065B1). Marketing had the largest absolute increase.
