    Reena is twice as old as Sunita. Three years ago, she was three times as old as Sunita. How old is Reena now?

    A)  6 yr                             

    B)  7 yr

    C)  8 yr                             

    D)  12 yr

    Correct Answer: D

    Solution :

    Let Sunita's present age be x yr. Then, Reena's present age = 2x yr. Three years ago, Sunita's age \[=(x-3)yr\] and Reena's age \[=(2x-3)yr.\] So, \[(2x-3)=3(x-3)\] \[\Leftrightarrow \] \[2x-3=3x-9\] \[\Leftrightarrow \]           \[x=6\] \[\therefore \] Reena's present age \[=2x=12\,yr\]
