Show answer & explanation
Correct answer: A
To find how much percent P is more than Q, use the formula: ((P - Q) / Q) * 100.
Substitute P = 9A and Q = 7A:
((9A - 7A) / 7A) * 100
= (2A / 7A) * 100
= (2 / 7) * 100
= 28.57...
Rounding to the nearest provided option gives 28.56%.
Final Answer: Option 1
