1. The problem is to find the total percentage from the given subject percentages. 2. To find the total percentage, we add all the individual percentages and then divide by the number of subjects. 3. The formula for average percentage is: $$\text{Total Percentage} = \frac{\text{Sum of all percentages}}{\text{Number of subjects}}$$ 4. Given percentages are: English = 72%, Maths = 82%, Science = 82%, Urdu = 73%, Geography = 85%, History = 79%, Islamiyat = 87%, Computing = 64%, Tarjama tul Quran = 87%. 5. Sum of percentages = 72 + 82 + 82 + 73 + 85 + 79 + 87 + 64 + 87 = 711 6. Number of subjects = 9 7. Calculate total percentage: $$\frac{711}{9} = 79$$ 8. Therefore, the total average percentage is 79%.
