Question

The luminosities of main sequence stars vary as a function of their mass approximately as M4. If a particular globular cluster contains no main sequence stars with masses higher than 1.1 MSun , estimate its age in Gyr given that the main sequence lifetime of a solar mass star is 1010 years. [Give numerical answer only to two significant digits]
