• Rakhi is 26 years younger than her mother.
• In 9 years, Rakhi's mother will be twice as old as Rakhi.
• What's the present age of Rakhi?
Let the present age of Rakhi and Rakhi's mother be x years and y years respectively.
Given that,
Rakhi is 26 years younger than her mother.
Therefore,
⟶ x = y - 26........ eq(1)
Again, it’s given that
In 9 years, Rakhi's mother will be twice as old as Rakhi.
After 9 years,
Age of Rakhi = (x+9) years
Age of Rakhi's mother = (y+9) years
A.T.Q :-
⟶ y + 9 = 2 ( x + 9)....... eq(2)
Now, put x = y - 26 in eq(2)
⟶ y + 9 = 2 y - 52 + 18
⟶ y = 43
Hence,
Present age of Rakhi's mother = 43 years.
Present age of Rakhi
= y - 26
= 43-26
= 17 years.
