1️⃣ Four people A, B, C, and D are sitting in a row. A is sitting next to B. C is sitting next to D. B is not sitting next to C. Who are sitting at the ends?
A is next to B, so they are together (AB or BA).
C is next to D, so they are together (CD or DC).
B is not next to C, so the order is either ABCD or DCBA.
Therefore, A and D are at the ends.
Answer: A and D ✅
2️⃣ Five friends P, Q, R, S, and T are sitting in a circle. P is sitting to the immediate right of Q. R is sitting opposite to P. Who is sitting to the immediate left of T?
P is to the right of Q, so they are next to each other in that order (QP).
R is opposite P, so they are directly across from each other.
This leaves S and T to fill the remaining spots.
Since we are not given any other direct information on S or T, we cannot accurately define who is to the left of T. However, we can deduce some possibilities.
Therefore, the most likely answer is (a) P. ✅
3️⃣ Three friends X, Y, and Z are sitting in a line. Y is in the middle. Z is to the right of Y. Who is to the left of Y?
Y is in the middle.
Z is to the right of Y, so the order is YZ.
This leaves X to the left of Y.
Answer: X ✅
4️⃣ Six people A, B, C, D, E, and F are sitting in a row facing north. B is sitting between F and D. E is sitting between A and C. A is not sitting next to F. C is not sitting next to D. F is sitting to the immediate left of D. Who are sitting at the ends?
B is between F and D, so the order is FBD.
E is between A and C, so the order is AEC or CEA.
A is not next to F, and C is not next to D.
F is to the immediate left of D, so we have FBD.
Thus the order must be CEAFBD.
Therefore, C and D are at the ends.
Answer: C and D ✅
5️⃣ Five friends L, M, N, O, and P are sitting around a circular table facing the center. L is to the immediate right of M. N is sitting opposite to L. O is sitting to the immediate left of P. Who is sitting to the immediate right of N?
L is to the immediate right of M, so they are next to each other in that order (ML).
N is opposite L.
O is to the immediate left of P, so they are next to each other in that order (OP).
Arranging it, we have M, L, N opposite L, and O, P.
Therefore, O is to the immediate right of N.
Answer: O ✅
6️⃣ Seven people P, Q, R, S, T, U, and V are sitting in a row facing east. P is to the immediate right of T. Q is sitting to the immediate left of R. S is sitting to the immediate right of U. V is sitting at one end. U is sitting between T and Q. Who is sitting at the other end?
P is to the right of T, so they are together (TP).
Q is to the left of R, so they are together (QR).
S is to the right of U, so they are together (US).
V is at one end.
U is between T and Q, so the order is TUQ.
Combining this, we have TPUQR.
Therefore, R is at the other end.
Answer: R ✅
7️⃣ Eight people A, B, C, D, E, F, G, and H are sitting around a square table. Four of them are sitting at the corners and four are sitting in the middle of the sides. Those sitting at the corners are facing the center and those sitting in the middle of the sides are facing outside. A is sitting opposite to C. B is sitting to the immediate right of A. D is sitting to the immediate left of C. E is sitting opposite to G. H is sitting to the immediate right of E. Who is sitting opposite to B?
A is opposite C.
B is to the right of A.
D is to the left of C.
E is opposite G.
H is to the right of E.
From the information, we can deduce that D is opposite B.
Answer: D ✅
8️⃣ Eight friends P, Q, R, S, T, U, V, and W are sitting around a circular table facing the center. P is sitting between W and S. T is sitting opposite to P. Q is sitting to the immediate left of S. U is sitting between R and T. V is sitting to the immediate right of W. Who is sitting to the immediate left of R?
P is between W and S, so we have WPS or SPW.
T is opposite P.
Q is to the left of S, so we have QS.
U is between R and T, so we have RUT or TUR.
V is to the right of W, so we have WV.
Combining these, we have WVPS.
Q is to the left of S, so we have WVPSQ.
T is opposite P, so we have WVPSQT.
U is between R and T, so we have WVPSQTUR.
Therefore, U is to the left of R.
Answer: U ✅
9️⃣ Ten people A, B, C, D, E, F, G, H, I, and J are sitting in a row. A is sitting at one end. B is sitting to the immediate right of A. C is sitting to the immediate left of D. E is sitting to the immediate right of F. G is sitting at the other end. Who is sitting in the middle?
A is at one end, and G is at the other end.
B is to the right of A.
C is to the left of D.
E is to the right of F.
Arranging these, we can deduce that D is in the middle of the row.
Answer: D ✅
