First of all, lets call these ladies:
1,2,3,4,5,6,7 and 8 inches tall
However the pose 1 will be in the first row and on the left and 8 will be in the second row on the right:
1 X X X
X X X 8
2 does not have too many choices:
1 X X X
2 X X 8 or
1 2 X X
X X X 8
Now it is time for 3
1 3 X X
2 X X 8
OR
1 X X X
2 3 X 8
OR
1 2 3 X
X X X 8
OR
1 2 X X
3 X X 8
Okay so far we have 4 different ways of placing 1,2,3 and 8 and my 2 minutes is UP!! So I would guess 4x3=12 or 4x4=16 and move on!
If I carry my solution, I will find the OA but this is not the point in GMAT.
Any under 2 min solutions ?

Can somebody comment on this.
It has more than 4 steps to solve and takes 4 or 5 mins to solve.
