A radioactive substance has a constant actity of 2000 disintegraion/mintue. The material is swparated into two fractions, one of which has an initlial activity of 100 disntegrationper secoundwhile the other fraction decays with t_(1//2) = 24 hour. The total activity in both samples after 48 hour of separation is:
