In which quarter of 2026 was the percentage increase in sales from the same quarter of 2025 the highest?
Answer and solution
Correct answer: A
Solution
Answer: A — Q1
1. Read the numbers on the image, not the sector angles: the equal-sized sectors are schematic, not proportional sales shares. The 2025 months Jan–Dec are 120,140,160,50,70,90,80,90,80,150,280,170.
2. The 2026 months Jan–Dec are 250,180,200,100,80,90,120,150,10,150,200,150. Missing values follow from quarter totals: May 2025=210−50−90=70; November 2025=600−150−170=280; December 2026=500−150−200=150.
3. Quarter totals: 2025=420,210,250,600 (annual 1480); 2026=630,270,280,500 (annual 1680). Q 3 2026=120+150+10=280.
Question-specific calculation:
The correct answer is A — Q 1.
Compare the same quarters in the two years:
Q 1: 2025 = 420; 2026 = 630.
Increase = (210 / 420) × 100 = 50%.
Q 2: 2025 = 210; 2026 = 270.
Increase = (60 / 210) × 100 = 28.57%.
Q 3: 2025 = 250; 2026 = 280.
Increase = (30 / 250) × 100 = 12%.
Q 4: 2025 = 600; 2026 = 500.
This is a decrease, not an increase.
The highest percentage increase is 50% in Q 1.
Verification: The highest percentage increase is 50% in Q 1.
