Between Y and A, the symbol ≤ is common, Hence, Y ≤ A is true obviously A ≥ Y is also true. Between X and E two opposite symbols, hence no conclusion can be drawn ∴ Only I follows 3. Between K and G, the Symbol < is common. Hence K < G follows. Between L and T, the symbol > is common. Hence L > T follows. ∴ Both I and II follow 4. Two opposite symbols between D and J. Hence, I does not follow. Between P and E, the symbol < is common. Hence P < E is true ⇒ E > P is also true ∴ Only II follows. 5. Between S and Z, the symbol ≤ is common. Hence, S ≤ Z true ⇒ Z ≥ S is also true. ∴ Either I or II follows 6. Two opposite symbols are there in between L and E. Hence I does not follow. Combining both the statements, we have P > N ≥ R. So P > R is true ⇒ R < P is also true. ∴ Hence only II follows 7. Combining both the statements we have K ≤ M ≤ T. So, K ≤ T is true ⇒ T ≥ K is also true. Two opposite symbols between U and M So, II does not follow. ∴ Hence, only I follows. 8. Combining we have, H > K ≥ G. So, H > G is true ⇒ G < H is also true. Combining we have N = K > O ⇒ N > O is true. ∴ Hence, both I and II follow ∴ Hence, either I or II follows. 10. Between Z and B there are two opposite symbols. So, I does not follow. Between S and B there are two opposite symbols. So, II does not follow. ∴ Hence, neither I nor II follows 11. Combining we have, N ≥ W > H So, N > H is true ⇒ H < N is also true Between W and T there are two opposite symbols, so no Conclusion can be drawn. ∴ Hence only I follows. 12. Combining we have F > R > H ≥ L From this, R ≥ L does not follow. F > L follows. ∴ Hence, only II follows 13. Combining we have J ≥ K < M > T Between K and T, two opposite symbols. So, neither I
nor II follows, but between I and II, one of the conclusions must be true but ∴ Hence either I or II follows. 14. Combining the statements we have F ≥ M > A > R < E Between F and E two opposite symbols. Hence neither I not II follows, But between I and II, one of the Conclusions must be true but which conclusion is definitely true we cannot say. ∴ Hence either I or II follows 15. Combining the statements we have A ≥ B < M > D = F A ≥ B is true ⇒ B ≤ A true but only B < A is false. M > F is true. ∴ Hence, only II follows 16. Between CB, and AE there are two opposite symbols. ∴ Hence, neither I nor II follows. 17. Between OD and MT there are two opposite symbols. 18. Between P and T, the symbol > is common So, P > T is true ⇒ T < P is also true. Between Q and S, the symbol ≥ is common So, Q ≥ S is true. ∴ Hence, only I and either conclusion II or III follows. 19. Between U and M, the symbol > is common So, U > M is true ⇒ M < U is true but M = U is false. Between S and C the symbol ≥ is common. So, S ≥ C is true ⇒ C ≤ S is true but only C > S is false. ∴ Hence, only I follows. 20. Between J and A, the symbol < is common. So, J < A is true ⇒ A > J is true. Between N and R, the symbol > is common So, N > R is true but N < R is false. Two opposite symbols between A and T. So III is false. ∴ Hence only I is true KEY: 1-2 2-1 3-5 4-2 5-3 6-2 7-1 8-5 9-3 10-4 11-2 12-1 13-2 14-4 15-5 16-3 17-3 18-3 19-2 20-1. SOME MORE EXAMPLES 1.
