To find the percentage difference between two numbers, we first need to calculate the absolute difference between them. In this case, the absolute difference between 176 and 200 is 24 (200 - 176 = 24).

Next, we need to find the average of the two numbers. The average of 176 and 200 is (176 + 200) / 2 = 188.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 176 and 200 is (24 / 188) x 100 = 12.77%.

This means that the second number (200) is 12.77% higher than the first number (176).
