Video Summary

In a problem-solving scenario, Eva begins with 2,022 tiles in a line. Adam removes every 6th tile, Beata every 5th from the remaining, and Kale every 4th from what's left after Beata. Finally, Doris removes all the remaining tiles. Observing a smaller case, beginning with 12 tiles and following the same removal sequence, half the tiles, six, remain for Doris to remove. Applying this pattern to the original 2,022 tiles, Doris removes half of them, resulting in 1,011 tiles being removed by Doris.
