In DS, how x>5 satisfies "is x>0"?
how x>5 satisfies "is x>0"? x>0 is- Besides x is positive, x>0 also mean x could be 1/2, 1 ,2,3, 5, 100. But x>5 means x could only be anything greater than 5, i.e. 5.5, 6, 10, but not 1, 2,3, 4. So how does x>5 satisfies "is x>0"? (It was in one of the Beat the GMAT videos)
