In an experiment, 200 children are arranged in 10 different rows, where each row contains 20 children. As a result, 20 columns are formed. From each of those columns, the shortest one is selected and from those 20 children, the tallest one is tagged X. These children now return to their initial places.
Now, the tallest child from each row is selected and the shortest from them is tagged Y.
Can you tell which one from the two (X and Y) is taller?
