Question
My sister was born 26 years after my mother was born, and I was born 28 years after my father was born. The current average age of my family is 32.5 years. Three years from now, my sister will get married and leave the family, and at that time, the average age of the family will be 41 years. What is the present age of my mother (in years)?
