The lady declared: My grand daughter is about as many days as my daughter is weeks, and my grand daughte is as many months as I am years. The three of us together are 140 years. The surveyor quickly took out her calculator and started punching in a few numbers to find the lady's age. Her calculator has a seven segment LCD displaye but she was puzzled to see the number so she did the calculations again, this time assuming 30 days in a month and 365 days in a year. This time the results were correct. Can you tell what did the calculator display showed, if you made the smae assumptions?
