• Devi's mother is three times Devi's age .
• Five years ago, Devi's mother was four times as old a Devi .
• What are the present ages of Devi and her mother's age?
Let Devi's age be x years.
Given that,
Devi's mother is three times Devi's age .
Then,
Devi's mother age will be = 3x
Again, it's given that
Five years ago Devi's mother was four times as old a Devi .
Five years ago,
Age of Devi = x - 5
Age of Devi's mother = 3x - 5
According to the question :-
⟶ 3x - 5 = 4(x - 5)
⟶ 3x - 5 = 4x - 20
⟶ -5 + 20 = 4x - 3x
⟶ x = 15
Hence,
Present Age of Devi x = 15 years
Present age of Devi's mother = 3x = 45 years.
