A brain-hacking puzzle that will stump even the smartest people - 1

Many answers were given with different reasoning, such as: 042, 420, 624, 660...

Someone gave the answer as 102. "For 682 and 614, we eliminate 6 and 8. We choose 2 in the units digit. For the 614 group, we eliminate 6 and choose 1 and 4 to try. For the 206 group, we choose 2 and 0 because 4 cannot be in the units digit (we've already chosen 2). So there are 3 digits to choose from: 0 and 1. Based on 614, we choose 1 for the hundreds digit and 0 for the tens digit. We have the number we are looking for, which is 102," Khanh Linh Nguyen explained.

What is your answer?
