Susan picked 3 times as much as 36 which is 3*36 = <<3*36=108>>108 apples

She gave out half which is 108*(1/2) = <<108*(1/2)=54>>54 apples

She now has 108-54 = <<108-54=54>>54 apples

Frank sold a third of 36 which is 36*(1/3) = <<36*(1/3)=12>>12 apples

Frank now has 36-12 = <<36-12=24>>24 apples

Altogether they now have 54+24 = <<54+24=78>>78 apples
