I think it's E, because they are both needed to answer the question but there is not enough data. We will need how many brought 3 people with them and how many brought 2 and 1 people/person.

Please correct me if I am wrong.

Agreed @Rakesh.

From statement-1 each entry passer can take three visitors with him. From statement-2 243x3 = 729.

So, a total of 729 visitors may be allowed but, it it is not necessary that each entry passer takes a three visitors along with him. He may take two or even one with him. So, answer should be D.

I think answer must be E because here it is clear number of visitors saw the exhibition is 729.
