product of the scores is 21000
21000= 7*3*(5^3)*(2^3)
Since there are no other points other than 7,5,3,2 answer should be 8 rounds .

I think this can be solved by prime factorization (because all numbers are primes):

21000/7 = 3000
3000/5 = 600
600/5 = 120
120/2 = 60
60/3 = 20
20/5 = 4
4/2 = 2
2

So we have 7*5*5*2*3*5*2*2 = 21000
So my answer would be 8.

you sure?
what if ross did not end by getting points in 10 rounds (say)
then the number of rounds he participated will be 18
so we can have numerous such examples
hence E

The question says that the product of his points is 21000.
If he does not get points in one round he gets zero points for that round, right?
Then the product of his points would always be zero if he gets no points for one round.

Think again..
Getting a zero is very different from getting no score..

Okay if no score is different from getting zero it makes sense.
Thanks

Correct answer is E and not A because we are given that there won't be any points awarded for rounds other than 1st four.

Thus, it may happen that he played 100 rounds out of only 8 rounds were there in which he was awarded some points.
