Asha is twice as old as Anita. Three years ago, she was three times as old as Anita. How old is Asha now?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 12 years
Both girls were 3 years younger three years ago, so the two conditions give one equation in Anita’s present age.
Let Anita’s present age be \(x\) years; Asha’s age is then \(2x\)
Three years ago: Asha \(2x-3\), Anita \(x-3\), and \(2x-3=3(x-3)\)
\(2x-3=3x-9\), so \(x=6\)
Asha’s present age \(=2\times6=12\) years
