Question 509124: A MOTHER TELLS HER DAUGHTER ."I WAS YOUR PRESENT AGE WHEN YOU WERE BORN".IF THE MOTHER IS 36 NOW,HOW OLD WAS THE DAUGHTER 5 YEARS BACK?
Answer by swincher4391(1107) (Show Source): You can put this solution on YOUR website!
When the daughter was born:
d[0] = 0
m[0] = d
Now after adding d years.
d[1] = d
m[1] = 2d
So we have that the mother is twice as old as the daughter.
If the mother is 36 right now, that means that the daughter is 18.
Then 5 years ago, the daughter was 13. <--- Answer
