Correct answer: C. 87.5%
Worked solution
- Total in 2022 = 400; in 2025 = 750.
- Increase = 350.
- Percentage growth = 350/400 × 100 = 87.5%.
Answer: 87.5%.
The idea
Percentage growth is always measured against the earlier value. Read the two numbers straight from the table rather than re-adding the rows — a totals column exists to be used.
Shortcut. The rise is 350 on a base of 400, which is 7/8. Since 1/8 = 12.5%, 7/8 = 87.5%.
Common trap. 75% echoes the 750 in the Total column and is the growth only as far as 700; the extra 50 on a base of 400 adds another 12.5 points.
