We'll use Susan as our base for this. She is 50 inches tall, and ignoring Myra or now, we move on to Elanie, who is said to be 2 inches shorter than Susan - therefore, Elanie is 48 inches tall. Now that we know this, we can return to Myra's information which says she is 3 inches taller than Elanie, which would mean she is in fact 51 inches tall.
