What is the percentage change in sales in September 2026 as compared to sales in September 2025?
Answer and solution
Correct answer: B
Solution
Answer: B — 87.50% decrease
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 B — 87.50% decrease.
September 2025 sales = 80.
September 2026 sales = 10.
Percentage change = ((10 − 80) / 80) × 100
= (−70 / 80) × 100
= −87.5%.
The negative sign indicates a decrease. Therefore, sales decreased by 87.50%.
Verification: The negative sign indicates a decrease. Therefore, sales decreased by 87.50%.

The negative sign indicates a decrease. Therefore, sales decreased by 87.50%.
G Strategy shortcut
Method: 10 is 1/8 of 80; remaining sales=12.5%, so decrease=87.5%.Verification: The negative sign indicates a decrease. Therefore, sales decreased by 87.50%.
