This question is from the kaplan subject test.

Question:
If N is any positive integer, how many consecutive
integers following N are need to insure that at least
one of the integers is divisible by another positive
integer m?
A. m - 1
B. m
C. m + 1
D. 2m
E. m2

Ans/Explanation:
A
One out of every m consecutive integers is divisible by the integer m. The wording of this question is difficult, so you might have thought the question was asking you to count N itself to get the correct answer.
But it was not, so m &#8722; 1 consecutive integers after N plus N itself are required in order to ensure that one
of these integers, including N, is a multiple of m.

i don't understand the question nor the explanation

Yeah do a search. There's been 2 threads in the last week. Takes too much time to time up a good explanation but I did it in one of those threads.
