For x to be divisible by 6, x must be divisible by both 2 and 3.grandh01 wrote:Is the integer X divisible by 6?
1) x + 3 is divisible by 3
2) x + 3 is a odd number
Statement 1: This implies x is divisible 3.
But we don't know whether x is divisible by 2 or not.
Not sufficient
Statement 2: This implies x is even, i.e. x is divisible by 2.
But we don't know whether x is divisible by 3 or not.
Not sufficient
1 & 2 Together: Now we know that x is divisible by both 2 and 3.
Hence, x is divisible by 6.
Sufficient
