Calculation of School Strength Increase in 2017
- The school strength in 2015 was 3000.
- According to the given condition, the strength increases and decreases by 20% every alternate year.
- In 2016, the strength would decrease by 20% to become 2400 (3000 - 20% = 2400).
- In 2017, the strength would increase by 20% from the previous year's strength of 2400.
- Calculating the increase: 2400 + (20% of 2400) = 2400 + 480 = 2880.

Percentage Increase in School Strength in 2017
- To find the percentage increase in strength from 2016 to 2017, we use the formula:
Percentage Increase = [(New Value - Old Value) / Old Value] x 100%
- Old Value (2016) = 2400 and New Value (2017) = 2880.
- Percentage Increase = [(2880 - 2400) / 2400] x 100% = (480 / 2400) x 100% = 20%.
Therefore, the school strength in 2017 would be 2880 students, and there would be a 20% increase in strength compared to the previous year.
