You can see from the graph, grams of radionuclide B initially is 32( at time=0).
Time it take to reach 16 gram is 8 days. ( At t=8 it shows gram as 16). Just see the lines in the graph.
So, time it takes to becomes half of the initial mass is 8 days. So, half life of isotope B is 8 days.
This is just a simple observation.
