    D)  24 yr

    Correct Answer: A

    Solution :

    6 yr back let Snehal's age be x yr and Sushil's age be 3x yr present age \[=(x+6)\] yr Sushil's present age \[=(3x+6)\]yr Snehal's age after 6 yr \[=(x+12)\]yr Sushil's age after 6 yr \[=(3x+12)\]yr \[(3x+12)=\frac{5}{3}(x+12)\]\[\Rightarrow \]\[9x+36=5x+60\]\[\Rightarrow \]\[4x=24\] \[\Rightarrow \]   \[x=6.\] Snehal's present age \[=(6+6)\] yr = 12 yr
