odd integer

by charmaine » Mon Sep 15, 2008 4:52 pm
is the integer n odd ?
1) n is divisible by 3
n is divisible by 5
ans is E
bt if we combine together it will be divisible by 15 meaning only all odd number (eg. 1 ,3,5,15) why is it E and not c

thankssss

n can be even or odd(e.g. 45 and 60, both of them are divisible by 3 and 5) even if you combine statements a and b.
