Since they are both on the main sequence but Betty is more luminous than Wilma, Betty must be located higher up on the main sequence. Therefore, Betty has a hotter surface temperature, is more massive, and has a larger radius. Betty will also evolve faster than Wilma, and if they were formed at the same time Betty will turn off the main sequence first.
