The mean is the average. To get an average age of three, 3 of her pets would have to 4 years old and the other 3 would be 2 years old. In ten years she would have 3 pets that are 14 and three that are 12, therefore the mean age of them would be= [(14*3)+ (12*3)]/6= 13 So in following the same concept, 20 years the mean age of her pets would be 23.
