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 167 and 125 is 42.

Next, we need to find the average of the two numbers. The average of 167 and 125 is (167+125)/2 = 146.

Now, we can calculate the percentage difference by dividing the absolute difference by the average and multiplying by 100. So, the percentage difference between 167 and 125 is (42/146) x 100 = 28.77%.

Therefore, the percentage difference between 167 and 125 is 28.77%. This means that 167 is 28.77% greater than 125.
