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

    A)  16 years                     

    B)  14 years

    C)  12 years         

    D)  6 years

    Correct Answer: C

    Solution :

          Let Siya's present age \[=x\text{ }years\] Then Riya present age \[=2x\text{ }years\] Three years ago \[(2x-3)=3(x-3)\] \[2x-3=3x-9\] Or \[x=6\] So, Riya's age \[=2x=2\times 6=12\text{ }years.\]
