The more massive star burns its fuel much faster then the lighter star.
Lifetime is proportional to about 1/M^2.5.
If star B is the sun, with a mainsequence lifespan of 10 billion years and a mass of 1, then star A, with a mass of 3*sun, will live for (1/3)^2.5 which is 0.064 or 6.4% of the suns lifespan giving star A a lifespan of in between 500 and 600 million years.
