Given: Nine persons A, B, C, D, E, F, G, H, and I 

Celebrated their birthdays in different months of the same year which are January, February, March, April, May, June, July, August, September.

January, March, May, July and August being the months having 31 days.

1) F celebrates his birthday in the month which has 30 days but before June.

2) Three persons celebrate birthday between F and E. E is exactly between G and C, and G is not the last person to celebrate birthday.

3) B is the first person to celebrate birthday.

4) Two persons celebrate birthday between A and H, and  A is not an immediate neighbour of B, but he celebrates his birthday in the month which has 31 days.

5) Two persons are there between D and I and D celebrates birthday before I. I is not celebrating after H.

Thus, the person immediately after B is D and person immediately before C is E, and there are five people between D and E.

Hence, the correct answer is "five".

Given: Nine persons A, B, C, D, E, F, G, H, and I 

Celebrated their birthdays in different months of the same year which are January, February, March, April, May, June, July, August, September.

January, March, May, July and August being the months having 31 days.

1) F celebrates his birthday in the month which has 30 days but before June.

2) Three persons celebrate birthday between F and E. E is exactly between G and C, and G is not the last person to celebrate birthday.

3) B is the first person to celebrate birthday.

4) Two persons celebrate birthday between A and H, and  A is not an immediate neighbour of B, but he celebrates his birthday in the month which has 31 days.

5) Two persons are there between D and I and D celebrates birthday before I. I is not celebrating after H.

Thus, G celebrates his birthday two months after the celebration of I.

Hence, the correct answer is "G".

Given word:- TECHNIQUE

Forward Pair - EI

Backward Pair - No such pair.

Thus, there is only one such pair of letters in the word “TECHNIQUE” which has as many letters between them as in the English alphabetical series (both in forward and backward directions).

Hence, the correct answer is One.

Given number: 82357947

Third digit from the left = 0

Seventh digit from the right = 1

Required sum = 0 + 1 = 1

Hence, 1 is the correct answer.

Given:

Row 1 - A, B, C. D. E, and F - Facing south.

Row 2 - P, Q, R, S, T, and U - Facing north.

Now,

1) R is sitting third to the left of T.

2) At least one person is sitting to the right of T. 

3) The one who is sitting opposite to R is sitting second to the right of E.

3) Only one person is sitting between E and C.

4) The number of persons sitting to the left of C is the same as the number of persons sitting to the right of B.

5) A is sitting second to the left of B. This is not possible in Case I (a) and Case II (a) so they get eliminated.

6) S is sitting third to the right of U.

7) Neither U nor P is sitting opposite to B. This condition is not satisfied in Case I (b) (i) and Case II (b) (i) so they get canceled.

7) F is sitting to the right of D who is not sitting opposite to S. This is not possible in Case I (b) (iI) so it gets eliminated.

The final arrangement is -

Only in AFE, the first person A is sitting exactly between the second and third person i.e. E and F in the final arrangement.

Hence, the correct answer is Only III.

Given:

Row 1 - A, B, C. D. E, and F - Facing south.

Row 2 - P, Q, R, S, T, and U - Facing north.

Now,

1) R is sitting third to the left of T.

2) At least one person is sitting to the right of T. 

3) The one who is sitting opposite to R is sitting second to the right of E.

3) Only one person is sitting between E and C.

4) The number of persons sitting to the left of C is the same as the number of persons sitting to the right of B.

5) A is sitting second to the left of B. This is not possible in Case I (a) and Case II (a) so they get eliminated.

6) S is sitting third to the right of U.

7) Neither U nor P is sitting opposite to B. This condition is not satisfied in Case I (b) (i) and Case II (b) (i) so they get canceled.

7) F is sitting to the right of D who is not sitting opposite to S. This is not possible in Case I (b) (iI) so it gets eliminated.

The final arrangement is -

All except QT have one person between them.

Hence, the correct answer is QT.

Given:

Row 1 - A, B, C. D. E, and F - Facing south.

Row 2 - P, Q, R, S, T, and U - Facing north.

Now,

1) R is sitting third to the left of T.

2) At least one person is sitting to the right of T. 

3) The one who is sitting opposite to R is sitting second to the right of E.

3) Only one person is sitting between E and C.

4) The number of persons sitting to the left of C is the same as the number of persons sitting to the right of B.

5) A is sitting second to the left of B. This is not possible in Case I (a) and Case II (a) so they get eliminated.

6) S is sitting third to the right of U.

7) Neither U nor P is sitting opposite to B. This condition is not satisfied in Case I (b) (i) and Case II (b) (i) so they get canceled.

7) F is sitting to the right of D who is not sitting opposite to S. This is not possible in Case I (b) (iI) so it gets eliminated.

The final arrangement is -

D, who is sitting immediate left of E, is sitting second to the left of A.

Hence, the correct answer is The one who is sitting immediate left of E.

Given:

Row 1 - A, B, C. D. E, and F - Facing south.

Row 2 - P, Q, R, S, T, and U - Facing north.

Now,

1) R is sitting third to the left of T.

2) At least one person is sitting to the right of T. 

3) The one who is sitting opposite to R is sitting second to the right of E.

3) Only one person is sitting between E and C.

4) The number of persons sitting to the left of C is the same as the number of persons sitting to the right of B.

5) A is sitting second to the left of B. This is not possible in Case I (a) and Case II (a) so they get eliminated.

6) S is sitting third to the right of U.

7) Neither U nor P is sitting opposite to B. This condition is not satisfied in Case I (b) (i) and Case II (b) (i) so they get canceled.

7) F is sitting to the right of D who is not sitting opposite to S. This is not possible in Case I (b) (iI) so it gets eliminated.

The final arrangement is -

All the given statements are true.

Hence, the correct answer is None of the statements is false.

Given:

Row 1 - A, B, C. D. E, and F - Facing south.

Row 2 - P, Q, R, S, T, and U - Facing north.

Now,

1) R is sitting third to the left of T.

2) At least one person is sitting to the right of T. 

3) The one who is sitting opposite to R is sitting second to the right of E.

3) Only one person is sitting between E and C.

4) The number of persons sitting to the left of C is the same as the number of persons sitting to the right of B.

5) A is sitting second to the left of B. This is not possible in Case I (a) and Case II (a) so they get eliminated.

6) S is sitting third to the right of U.

7) Neither U nor P is sitting opposite to B. This condition is not satisfied in Case I (b) (i) and Case II (b) (i) so they get canceled.

7) F is sitting to the right of D who is not sitting opposite to S. This is not possible in Case I (b) (iI) so it gets eliminated.

The final arrangement is -

Three persons are sitting between B and D who sits opposite to T.

Hence, the correct answer is Three.

The pattern followed here is;

As per the English alphabetical series,

C + 4 = G; G + 3 = J; J - 2 = H,

L + 4 = P; P + 2 = R; R - 1 = Q,

P + 4 = T; T + 3 = W; W - 2 = U,

K + 4 = O; O + 3 = R; R - 2 = P,

I + 4 = M; M + 3 = P; P - 2 = N

Hence, 'LPRQ' is the odd one out.
