Worked Solution

Step 1: Compare the thousands digit — all four numbers have 4, so move to the hundreds digit. Step 2: Compare hundreds digits: 4035 (hundreds = 0), 4053 (hundreds = 0), 4305 (hundreds = 3), 4503 (hundreds = 5). Step 3: 4035 and 4053 share hundreds digit 0. Compare their tens digits: 4035 has 3, 4053 has 5. So 4035 Step 4: Order: 4035, 4053, 4305, 4503. The second smallest is 4053. Answer: 4053

Correct answer: 4053
