Hundred thousandsTen thousandsThousandsHundredsTensUnits
Player A310500
Player B309500
Player C295500
Player D315500

Next, look at each column in turn from the left:

• the smallest digit in the hundred thousands column is 2, so Player C earns the lowest amount
• the smallest digit in the ten thousands column is 0, so Player B earns less than Players A and D

From highest to lowest, the order is:

1. Player D - £315,500
2. Player A - £310,500
3. Player B - £309,500
4. Player C - £295,500
