Question

Planting Trees
You just brought TEN trees..
You want to plant them in FIVE rows
with FOUR trees in each row.
How are you going to do it?​

Answer 1

Answer:

Since there are only 10 trees which need to be planted in five rows of four each, it is clearly evident that the trees can't be planted in parallel rows. Rather, the rows have to intersect each other. Something like this:

Step-by-step explanation:

In the above pattern, assume that the blue lines are the rows and the brown crosses are the trees. In this way, some of the trees stand common for two rows, thus making it possible to have five rows of four trees each.

That's a beautiful star shaped grove we have and I guess the puzzle is solved. Peace!
