Coded Inequalities for competitive exams
Coded inequalities is the easiest and important topic in competitive exams. We can easily score in this topic when we know the logic. Lets begin it.
Coded inequalities based on the mathematical relational operators like <, > <=, >= , =.
If you are well in using these symbols then you can easily crack this section. Lets go for a small table which makes all the combination of using the above relations.
The above all are the combinations of possibilities. That means if you find the above first two combinations and if in your answer the result is available then it is correct answer otherwise wrong answer.
Ex: a<b,b<c
rusult is : a<c or c>a
Q: a<b, b<c
Conclusions: 1. c<a
2. a<c
In the above two conclusions 2nd conclusion is correct, and first conclusion is wrong.
To understand this concept you have to practice more examples.
Here are some question you can solve and Improve your score in this section.

- A<C , C>D , A>E
- E<C
- D<A
- Only Conclusion 1 Follows
- Only Conclusion 2 Follows
- Conclusion 1 and 2 Follows
- Neither Conclusion 1 and 2 Follows
- Either Conclusion 1 or 2 Follows
