From (1). 3n/15 is integer when n is multiple of 5 . so n=5, 10, 15, 20...BTGmoderatorDC wrote:If n is an integer, is n/15 an integer?

n/15 is an integer 15, 45 or multiple of 15 only and not when is 5, 10, 20, 25 etc, So clearly the Information is not sufficient to the answer the question.
from (2) 8n/15 is an integer for all multiples of LCM of 8 and 15. i.e 8n/15 is integer for all multiples of 120. n=120, 240, 360.
As 15 is factor of 120, it will be factor of every multiple of 120. Hence n/15 will always be an integer. Hence the information is sufficient.
Answer is B
