Answer to Question 1

Less than 0.1

Answer to Question 2

The stars are plotted on an H-R diagram. Note is made of the mass of the stars which are just turning off the main sequence and becoming red giants. The age of these stars is the age of the cluster. Basically, the lower down the main sequence we find stars evolving into the giant branch, the older the cluster is.
