Hey guys, would be happy so see how you guys solve this one.

thanks.



2x + 2 is multiple of y

If x is 1 Then 2x + 2 = Odd/y

If x is 2 then 2x + 2 = Even /y

Statement 1 insuff

Y is multiple of x

Again dosent provide any number, more over we can not determine what x is...

Statemnt 2 insuff.

Together also we can not determine...

My take on this.

Statement 1: 2x+2 is a multiple of y => cannot imply that 2x is also a multiple of y
not sufficient.
Statement 2: y is a multiple of x => cannot prove that 2x is also a multiple of y
not sufficient.

IMO "E"
