A B C D E F – six people ordered according to ascending heights

Now it’s quite clear that ‘A’ takes first row left most position, and ‘F’ takes second row right most position.

__ __ F
A __ __

Now we are left with B, C, D and E.
The position above ‘A’ can be filled in three ways (leaving the tallest among them for the next position, as the person in next position should be taller than the person in this one.)

3 __ F
A __ __

Now we are left with three people.

The position below ‘F’ can be filled in two ways (leaving the shortest among them for the previous position, as the person in previous position should be shorter than the person in this one.)

3 __ F
A __ 2

Now we are left with two people, the taller one takes the position adjacent to F and the shorter one takes the position adjacent to A. i.e. only one possible way.

So, Total no. of ways = 3*2*1*1 = 6
