Given:

Total students = 1500
Present students = 1200

Step 1: Use the formula

Percentage=Present/Total​×100

Step 2: Substitute values

=1200​/1500×100

Step 3: Solve

$$=0.8\times 100=80\%$$

Explanation

Assume price = 100
After +20% → 120
After −20% → 96

So the final price is less than the original.
