Reasoning – Inequality Advanced (Either-Or, Mixed Cases & Tricks)

Advanced inequality reasoning

In advanced inequality, questions include mixed symbols and either-or cases. You need to carefully connect statements and check conclusions logically.


Mixed Inequality

Example:
A > B ≤ C < D

Read step-by-step:
A > B
B ≤ C
C < D

Conclusion: A > D ❌ (Cannot be determined)


Important Rule

  • If direction is clear → Answer definite
  • If direction changes → Check carefully

Either-Or Concept

When two conclusions are opposite, one must be true.

Example:
A > B
Conclusions:
1) A > B
2) A ≤ B

Answer: Either 1 or 2 is true ✔


When to Use Either-Or

  • Two conclusions are opposite
  • Cannot be true together
  • No definite answer individually

Example Questions

Q1:
A > B ≥ C
→ Is A > C?

Answer: Yes ✔

Q2:
A ≥ B ≤ C
→ Is A > C?

Answer: Cannot be determined ❌


Practice Questions

Q1: A > B ≥ C → Is A > C?

Q2: A ≤ B ≥ C → Is A > C?

Q3: A > B, B ≤ C → Is A > C?


Answers

Q1: Yes
Q2: Cannot be determined
Q3: Cannot be determined


Quick Tricks

  • Convert into chain step-by-step
  • Do not assume missing links
  • Check each conclusion independently

Final Tip

Practice mixed inequality daily. It is a scoring topic if you avoid assumptions and follow logic.
