two inequalities can be added if signs are same. However other are not true as we cannot multiply divide with variable without knowing its sign. We can only add and subtract

Bottom question answer E

1st one is 3, which you get when you add both the inequalities
2nd one is E, as even for x=0.9999, x3 will be less than 1.

Please help
­Worth noting though that such type of pure algebraic questions are no longer a part of the DS syllabus of the GMAT.­

­DS questions in GMAT Focus encompass various types of word problems, such as:
  • Word Problems
  • Work Problems
  • Distance Problems
  • Mixture Problems
  • Percent and Interest Problems
  • Overlapping Sets Problems
  • Statistics Problems
  • Combination and Probability Problems

While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won't encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."­

­Check GMAT Syllabus for Focus Edition­

Hope it helps.­
