Is x>0 i.e x>0 or x<0
Statement 1
x has only one multiple
Every number except zero has an infinite number of multiples.
E.g
multiples of 2 = 2, 4, 6, 8, 10...........................n
multiples of 3= 3, 6, 9, 12, 15.........................n
But zero has only one multiple which is zero itself x = 0 , hence statement 1 is INSUFFICIENT.
Statement 2
x has an infinite number of factors
Every number has an infinite number of factors except zero(0)
E.g
Factor of 2 = 2
3 = 3
4 = 4, 2, 1 e.t.c
but factors of zero(0) = 1, 2, 3, 4, 5, 6, 7,............................n
x = 0, hence statement 2 is INSUFFICIENT.
Both statement alone are SUFFICIENT.
