Example 5:-
If ‘WORK’ is coded as ‘4-12-9-16’, then how will you code ‘WOMAN’?
(a) 4-12-14-26-13     (b) 4-26-14-13-12  c) 23-12-26-14-13

Then,

Here, each letter is coded by the numerical value obtained by subtracting its ‘position value’ in English alphabetical order, from 27, e.g. letters W, O, M, A, N are at 23rd, 15th, 13th, 1st and 14th position in alphabetical order. So, their codes are (27 – 23), (27 – 13), (27 – 1), (27 – 14) i.e. 4, 12, 14, 26, 13, respectively i.e. their backward order position.

Solutions
1. Two opposite symbols between E and N, Hence, I does not follow. Between E and C the symbol > is common. Hence, E > C is true, obviously C < E is also true.

∴ Only II follows.

2. 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
9. Combining we have, G H M. So, G M is true.

∴ 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
which conclusion must be true we cannot say.

∴ 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.
∴ Hence neither I nor II follows

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
