From (i) and (ii), home à rh (v)

From (ii) and (iii), charity à na … (vi)

From (ii) and (iv), at à ek … (vii)

From (ii), (v), (vi) and (vii), begins à sa … (viii)

From (i) and (iv), a à co … (ix)

From (iii) and (iv), store à ku … (x)

From (iv), (vii) (ix) and (x), station à ze (xi)

From (iii), (vi) and (x), find/good à dn/he … (xii)

1. b                  2. c                  3. b                  4. c                  5. a

6. c;     Some heads are tails (1) à conversion à Some tails are heads (I). Hence conclusion I follows. There is no negative statement, Hence the possibility in II exists. Hence conclusion II follows.

7. c;     All comments are reviews (A) + All reviews are observations (A) = A + A = All comments are observations (A), Hence I does not follow. Again, there is no negative statement. Thus, a negative conclusion cannot follow. Hence II also does not follow.

8. 5;     No mountain is a cliff (E) + some cliffs are rocks (I) = E + I = O* = Some rocks are not mountains. Hence conclusion I does not follow. But II follows.

9. d;     All amounts are principles (A) + Some principles are balances (I) = A + I = No conclusion. But the possibility in I exists. Hence conclusion I follows. Again, some principles are balances (I) à conversion à Some balances are principles (I). Hence II does not follow.

10. d;   All posts are mails (A) + No mail is a letter (E) = A + E = E = No post is a letter. Hence I follows, But Il does not follow.

11. b;   Here I is added to the first digit in each number. Then the numbers become

369      414      858      737      925

After interchanging the positions of the first and the second digits, the new numbers will

become

639      144      588      377      295

Hence the highest number is 639. So, the first digit of the highest number is 6.

12. c;   The sum of the second and the third digit of the following numbers:

758 à 5 + 8 = 13

314 à 1 + 4 = 5

637 à 3 + 7 = 10

825 à 2 + 5 = 7

269 à 6 + 9 = 15

Hence the sum of second and third digit of the number 637 is even.

13. e;   According to the question the new numbers become

269                  314                  758                 637                  825

                                                                           

When the position of the first and the third digit are interchanged,

the new numbers become

862      313      757      636      428

Thus, the lowest number is 313. So, second digit of the lowest number is 1.

14. d;   The third highest number is 637. And the second lowest number is 314.

Reqd number = 637 - 314 = 323.

15. c;   After arranging in ascending order within the numbers, we get

269      134      578      367      258

The second lowest number is 258. The second digit of the second lowest number is 5.

(16 - 20):

Given δ à < % à >, © à <, * à =, $ à >

16. a;   K δ D ⇒ K < D … (i)

               D © W ⇒ D < W … (ii)

               W * Z ⇒ W = Z … (iii)

               Combining (i), (ii) and (iii), we get K < D < W = Z

            Thus, K < Z or Z > K is true. Hence I (Z % K) is true. Again, K < W is true.

            Hence II (K © W) is true. So, both conclusions I and II are true.

17. a;   Given  F © N ⇒ F < N … (i)

                        N * K ⇒ N = K … (ii)

                        K δ D ⇒ K < D … (iii)

            Combining (i), (ii) and (iii), we get F < N = K < D

            Thus, N < D or D > N is true.

            Hence either conclusion I (D = N) or conclusion II (D > N) is true.

18. b;   Given  B * R ⇒ B = R … (i)

                        R $ J ⇒ R > J … (ii)

                        J % M ⇒ J > M … (iii)

            Combining (i), (ii) and (iii), we get B = R > J > M

            Thus, R > M or M < R is true.

            Hence conclusion I (M © R) is true.

            Again B > J or J < B is true.

            Hence II (J δ B) is true.

19. d;   Given D $ T ⇒ D > T … (i)

T % M ⇒ T > M … (ii)

M © K ⇒ M < K … (iii)

            Combining (i), (ii) and (iii), we get D > T > M > K

            Thus, we can’t compare T and K.

            Hence conclusion I (K % T) is not true.

            Again D > M or M < D is true.

            Hence II (M © D) is true.

20. e;   Given  V % R ⇒ V > R … (i)

            R δ N ⟹ R < N … (ii)

N $ J ⟹ N > J … (iii)

            Combining (i), (ii) and (iii), we get V > R < N > J

            Thus we can’t compare R and J, or V and N.

            Hence neither conclusion I (J © R) nor II (V % N) is true.

21. b;   Given

read your book à 9 2 7 … (i)

From I, book on shelf à 7 3 8 … (ii)

From (i) and (ii), book à 7

From II, your hook shelf à 2 7 8 … (iii)

From (i) and (iii), your/book à 2/7

Hence only I is sufficient to answer the question.

22. b;   From I,

Hence V is either maternal or paternal grandfather of R. Hence I alone is not sufficient to answer the question.

From II,

Thus, V is paternal grandfather of R. Hence II alone is sufficient to answer the question.

23. a;   From I,

           

            Hence D is

            From II,

           

            Hence D is

24. a;   From I,

Male teacher =   

From II,

Every 10 girls has one female teacher. But exact no. of boys is not given.

Hence we can`t find the number of teachers in the dance class even by combining both statements.

25. d;  

Combining both I and II we get,

Hence J is fourth from the left.

(26 - 30):

           

            26. d                27. a                28. b                29. b                30. c

            31. c                32. b                33. d                34. d                35. d

36. e;  

37. c;   The sixth element to the tight of fifteenth from the right = (15 - 6 =) 9^th from the right.

Now, 9th from the right is *.

38. d;   The corresponding element of each group is four positions after that of the previous group.

39. e;   New series A © Z @ W # β X J Σ D + Q € Y L G * M Ω N % U

Hence eleventh element from the left end is D.

40. a;   β5X, +7Q, *6M, Ω2N, %8U. Hence more than three.
