One day recently, out of the blue, my sister Alice made this remark about her three daughters and herself:
“A few years from now, Daisy and I will be one and a half times as old as Beryl and Cheryl. The same number of years ago, when they were still all teenagers, Beryl and I were, in total, twice as old as Cheryl and Daisy. Also, Cheryl and I were one and a half times as old as Beryl and Daisy.”
What are their four ages now?
