Given information:
- The strength of a school increases and decreases in every alternate year by 10%.
- It started in 2000 and increases in 2001.
To find: The strength of the school in 2003 as compared to that in 2000.
Solution:
Let's assume the strength of the school in 2000 to be 100.
- In 2001, the strength increases by 10%, i.e., the strength in 2001 = 100 + (10/100)*100 = 110.
- In 2002, the strength decreases by 10%, i.e., the strength in 2002 = 110 - (10/100)*110 = 99.
- In 2003, the strength again increases by 10%, i.e., the strength in 2003 = 99 + (10/100)*99 = 108.9.
Therefore, the strength of the school in 2003 as compared to that in 2000 is increased by (108.9-100)/100 * 100 = 8.9%.
Hence, option 'A' is the correct answer.
Note: The key to solving this problem is to use the concept of successive percentage change.
