Answer 2

Answer:

Step-by-step explanation:

1. Let the original strength of the school be x.

2. It was increased by 10% during one year. So,

x×10/100=x/10

x+x/10=11x/10

3. It was increased by by 20% during the next year. So,

11x/10×20/100=11x/50

11x/10+11x/50=66x/50.

4.After 2 years the total number of students became 528.

So,

66x/50=528.

x=528×50/66=400.

5.So, the original strength of the school is 400 students.
