A.M>=G.M

The product of n positive numbers is unity.Then their sum is
a.a positive integer b.divisible by n
c.equal to n + 1/n d.never less than n

Let the numbers be a1,a2,a3.......an
Applying A.M>=G.M we get,
a1+a2+a3+.............+an/n >=1
a1+a2+a3......+an >=n

So answer must be a,b and d.....but ans given is d....failasy kaha hai?

The sum will not always be a positive integer. Take 12, 1 and 2 for example.
Similarly the sum will not always be divisible by n.
