I have no clue about the 1st question. Help would be much appreciated! :shock:

Please correct the typo in the 3rd q.

Heres my solution for the 2nd.

Since p = 1*2*3....*30, 3*(any answer choice) is a factor of p. So the greatest integer (from the given choice) for which 3k is a factor of p is 18 (E)

PS. Even 30*3 is a factor of p

Ad 1:

7 options for picking first person

10! / (8!2!) for second job = 45 combinations

7*45 = 315
