a) Between 10 and 20
b) Between 20 and 30
c) Between 30 and 40
d) Greater than 40
e) Less than 40

2. If n is a positive integer and the product of all the integers from 1 to n, inclusive, is a multiple of 990, what is the least possible value of n?

a) 10
b) 11
c) 12
d) 13
e) 14


Please help me out guys. Thanks.

I am sorry but I think I should not have posted the GMAT Prep questions directly in this forum. Sorry for that. But these two questions were bugging me greatly. I got the solution of the first question from a different post but still not sure about the second one.

As my GMAT exam is on the 1st of December, I could use all the practice that I can access to. Thanks.

for the first question I would say D, but simply because if such a question comes out at the GMAT, and any of the A - B - C would be correct, then somebody might argue that even E would be correct...so, don't lose time and try with D!
