To find the percentage difference between two numbers, we first need to find the absolute difference between them. In this case, the absolute difference between 153 and 200 is 47 (200 - 153 = 47).

Next, we need to find the average of the two numbers. The average of 153 and 200 is (153 + 200) / 2 = 176.5.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 153 and 200 is (47 / 176.5) x 100 = 26.63%.

This means that the second number (200) is 26.63% greater than the first number (153).
