Last Updated On: Fri Aug 28 2026Caselet
A company sold 200 units in 2023. Its sales rose by 25% in 2024 and then fell by 20% in 2025, each change measured against the previous year.
Question
What was the net percentage change in sales from 2023 to 2025?
Table built from the caselet
| Year | Change | Units sold |
|---|---|---|
| 2023 | - | 200 |
| 2024 | +25% | 250 |
| 2025 | -20% | 200 |
Solution
- 2024 sales = 200 x 1.25 = 250.
- 2025 sales = 250 x 0.80 = 200.
- Net change = (200 - 200) / 200 x 100 = 0%.
- Sales in 2025 were the same as in 2023.
