In a dance competition the points in each round for the first,second,third and fourth position were 100,50,20,10 . No other points were given. Ashita participated in several rounds in the competition and the product of her score was 50000. In How many rounds did she participate?	Options
A) 3 B) 2 C) 1 D) 5 E) Cannot be determined
Correct answer is E because we are given that there won't be any points awarded for rounds other than 1st four position.   Thus, it may happen that she played 15 rounds out of only 5 rounds were there in which she was awarded some points.
