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.

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.

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

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.
