The Correct Option is B
Solution and Explanation
Ten persons- I, J, K, L, M, N, O, P, Q and R were born on either on 13th or 14th of January, February, March, April and May.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
O is 13 years old and was born in April. The age and the birth date of a person are not the same.
Thus, O was born on 14th April.
Five persons were born between O and N.
Three persons were born between R and J.R is 14 years old.
The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
P was born immediately before L but not in the same month.
The difference between the ages of M and Q is 3 years and 3 months.
Thus, M/Q were born in 2007/2010.
M and Q were born on the same date.
I was born after Q but before K.
Thus, case 1a and case 2 are invalid.
Therefore, the final arrangement is:
K is the youngest person.
So, the correct option is (B): K.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.

Ten persons- I, J, K, L, M, N, O, P, Q and R were born on either on 13th or 14th of January, February, March, April and May.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
O is 13 years old and was born in April. The age and the birth date of a person are not the same.
Thus, O was born on 14th April.
Five persons were born between O and N.
Three persons were born between R and J.R is 14 years old.
The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
P was born immediately before L but not in the same month.
The difference between the ages of M and Q is 3 years and 3 months.
Thus, M/Q were born in 2007/2010.

The Correct Option is A
Solution and Explanation
Ten persons- I, J, K, L, M, N, O, P, Q and R were born on either on 13th or 14th of January, February, March, April and May.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
O is 13 years old and was born in April. The age and the birth date of a person are not the same.
Thus, O was born on 14th April.
Five persons were born between O and N.
Three persons were born between R and J.R is 14 years old.
The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
P was born immediately before L but not in the same month.
The difference between the ages of M and Q is 3 years and 3 months.
Thus, M/Q were born in 2007/2010.
M and Q were born on the same date.
I was born after Q but before K.
Thus, case 1a and case 2 are invalid.
Therefore, the final arrangement is:
I was born in 2007. Thus, I is 15 years old.
So, the correct option is (A): 15 years.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.

The Correct Option is D
Solution and Explanation
Ten persons- I, J, K, L, M, N, O, P, Q and R were born on either on 13th or 14th of January, February, March, April and May.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
O is 13 years old and was born in April. The age and the birth date of a person are not the same.
Thus, O was born on 14th April.
Five persons were born between O and N.
Three persons were born between R and J.R is 14 years old.
The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
P was born immediately before L but not in the same month.
The difference between the ages of M and Q is 3 years and 3 months.
Thus, M/Q were born in 2007/2010.
M and Q were born on the same date.
I was born after Q but before K.
Thus, case 1a and case 2 are invalid.
Therefore, the final arrangement is:
Eight persons were born between J and K.
So, the correct option is (D): More than 5.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.

The Correct Option is C
Solution and Explanation
Ten persons- I, J, K, L, M, N, O, P, Q and R were born on either on 13th or 14th of January, February, March, April and May.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
O is 13 years old and was born in April. The age and the birth date of a person are not the same.
Thus, O was born on 14th April.
Five persons were born between O and N.
Three persons were born between R and J.R is 14 years old.
The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
P was born immediately before L but not in the same month.
The difference between the ages of M and Q is 3 years and 3 months.
Thus, M/Q were born in 2007/2010.
M and Q were born on the same date.
I was born after Q but before K.
Thus, case 1a and case 2 are invalid.
Therefore, the final arrangement is:
Except (3), all are false.
So, the correct option is (C): N was born before L but not in the year 2008.
The persons born in January were born in 2006, persons born in February were born in 2007, persons born in March were born in 2008, and so on.
Therefore, the tabular representation will be:
| Month & Year | Date | Person |

The age of persons is considered as of the year 2022.
Thus, R was born in the year 2008. (2022-14 = 2008)
So, R should be born on 13th March 2008.
| Case 1 | Case 2 | ||

| April 2009 | 13th | L | L |
| 14th | O | O | |
| May - 2010 | 13th | J | |
| 14th |
Thus, M/Q were born in 2007/2010.
M and Q were born on the same date.
| Case 1 | Case 1a | Case 2 | ||
| Month & Year | Date | Person | Person | Person |
| January - 2006 | 13th | J | J | |
| 14th | N | N | ||
| February - 2007 | 13th | M/Q | ||
| 14th | M/Q | M/Q | ||
| March - 2008 | 13th | R | R | R |
| 14th | P | P | P | |
| April 2009 | 13th | L | L | L |
| 14th | O | O | O | |
| May - 2010 | 13th | M/Q | J | |
| 14th | M/Q | M/Q |
Thus, case 1a and case 2 are invalid.
Therefore, the final arrangement is:
| Case 1 | ||
| Month & Year | Date | Person |
| January - 2006 | 13th | J |
| 14th | N | |
| February - 2007 | 13th | Q |
| 14th | I | |
| March - 2008 | 13th | R |
| 14th | P | |
| April 2009 | 13th | L |
| 14th | O | |
| May - 2010 | 13th | M |
| 14th | K |
So, the correct option is (C): N was born before L but not in the year 2008.

Top Questions on Seating Arrangement
Four teams – Red (R), Blue (B), Green (G), and Yellow (Y) – are competing in the final four rounds of the Inter-School Science Olympiad, labeled Round A, Round B, Round C, and Round D. Each round consists of one match between two teams, and every team plays exactly two matches. No team plays the same opponent more than once.
The final schedule must adhere to the following rules:
- Rule 1 (Consecutive Play): The Green team (G) must play their two matches in consecutive rounds.
- Rule 2 (Fixed Appearance): The Yellow team (Y) must play in Round B.
- Rule 3 (Positional Constraint): The Red team (R) must play against the Blue team (B) in a round that is immediately before a round in which neither R nor B is playing.
- Rule 4 (Timing): The Blue team's (B) first match must occur in an earlier round than the Green team's (G) first match.
- Rule 5 (Opponent Link): The team that plays against the Red team (R) in the round that is not against the Blue team (B), is the same team that plays in Round D.
