People: P, Q, R, S, T, U, V, and W.

1). U sits fourth to the right of Q.

2). Q and U are not sitting at the extreme end of the line.

3). Q and U face the opposite direction to each other.

On Combining these 3 statements, we get 4 possible cases.

Case I: When Q is facing North and sitting 2nd from the extreme end, so U will face South.

Case II: When Q is facing North and sitting 3rd from the extreme end, so U will face South.

Case III: When Q is facing South and sitting 3rd from the extreme end, so U will face North.

Case IV: When Q is facing South and sitting 2nd from the extreme end, so U will face North.

This implies V faces north direction as P neighbor's W face north direction.

Since S is left, thus it occupies the left position and will face in North direction, because people sitting in Extreme ends are facing in same direction.

The final arrangement:

Now, R is sitting second to the right of U.

And R is facing south direction, so T is in immediate right position from R.

Hence, T is at immediate right position.

Since S is left, thus it occupies the left position and will face in North direction, because people sitting in Extreme ends are facing in same direction.

The final arrangement:

Hence, Only One people sit between V and W is the correct statement.

Persons: I, J, K, L, M, N, O, and P.

1) K was born on 10^th September.

2) N was born in July.

3) Two persons were born between N and O. So, O must have born on either 16^th August or 10^th June.

4) L was born just before J and both were born in the month, which has 30 days. So, case 2 would be invalid as it contradicts the given statement.

5) M was born after I, who was born after P.

Hence, M was born on 16^th September.

Persons: I, J, K, L, M, N, O, and P.

1) K was born on 10th September.

2) N was born in July.

3) Two persons were born between N and O. So, O must have born on either 16th August or 10th June.

4) L was born just before J and both were born in the month, which has 30 days. So, case 2 would be invalid as it contradicts the given statement.

5) M was born after I, who was born after P.

Hence, N was born just after J.

Persons: I, J, K, L, M, N, O, and P.

1) K was born on 10^th September.

2) N was born in July.

3) Two persons were born between N and O. So, O must have born on either 16^th August or 10^th June.

4) L was born just before J and both were born in the month, which has 30 days. So, case 2 would be invalid as it contradicts the given statement.

5) M was born after I, who was born after P.

Hence, L is the oldest.

Persons: I, J, K, L, M, N, O, and P.

1) K was born on 10^th September.

2) N was born in July.

3) Two persons were born between N and O. So, O must have born on either 16^th August or 10^th June.

4) L was born just before J and both were born in the month, which has 30 days. So, case 2 would be invalid as it contradicts the given statement.

5) M was born after I, who was born after P.

Hence, one person was born between P and O.

Persons: I, J, K, L, M, N, O, and P.

1) K was born on 10^th September.

2) N was born in July.

3) Two persons were born between N and O. So, O must have born on either 16^th August or 10^th June.

4) L was born just before J and both were born in the month, which has 30 days. So, case 2 would be invalid as it contradicts the given statement.

5) M was born after I, who was born after P.

Hence, O was born on 16^th August.

Combined Statement: A > E ≥ G < K ≤ D and A > E ≥ G < K ≤ L

I. G < L → True (As, G < K ≤ L Here, in between G and L common sign is < towards L. So, G < L)

II. D > G → True As, G < K ≤ D Here, in between D and G common sign is < towards D. So, D > G)

Hence, both I and II follows.
