The correct answer is 600. It’s given that 210 is p% greater than 30. It follows m that 210 = (1+p100 ). Dividing both sides of this equation by 30 yields 7 = 1+p100. Subtracting 1 from both sides of this equation yields 6 = p100 Multiplying both sides of this equation by 100 yields p = 600. Therefore, the value of p is 600.
