Dear Vini,
We know that after inserting dielectric capacitance became k times of initial value .
In this case capacitance of capacitor will become 3 times of initial value and hence charge stored will also be 3 times of initial value ..
so charge stored will be 21 x 3 = 63micro C..

Thanks and Regards
Adarsh
