Well, Kritikaprasad101, all I can say is "Have at it, dear student!"  WE don't do your homework for you.  YOU get to do that.

Further, never post a question that says something like "Shown here are the various prizes..."  and then don't show the prizes... tsk, tsk.  Be more careful.  Well, actually, be industrious and do your work.  

Have a nice day.  Come back if you get stuck on one particular aspect of the question.  And... show us your work to this point so we will be able to respond helpfully.
