Jill = J
Beth = B
Meg = M
Sounds like Beth is the youngest.
J = M - 2
B = 1/2 M
Explanation
B = 1/2 M. This means that Beth is 1/2 as old as Meg.
J = M - 2 This means that Jill is 2 years younger than Meg.

Comment
I don't think you can go to three statements. You need one more statement than you've given us.

IMAGE 2: symmetric because, well, it's symmetric.
IMAGE 3: negatively skewed because it is skewed to the left.
