The first clue states: "C is to the left of A and to the right of E." This gives us a partial arrangement:
E C A
The second clue states: "B is to the left of D and to the right of A." This gives another partial arrangement:
A B D
We need to combine the two partial arrangements (E C A and A B D) into a single sequence for the five members sitting in a row.
By linking the common member 'A', we get the complete order:
E C A B D
There are five members (E, C, A, B, D) sitting in a row. The middle position is the 3rd position.
In the arrangement E C A B D, the person occupying the 3rd position is A.
Therefore, A is sitting in the middle.
Seven people, A, B, C, D, E, F and G, are sitting in a straight row facing the north. Only two people sit to the left of C. Only two people sit between A and B. B sits to the left of A. E is an immediate neighbour of A to the right. Only one person sits to the right of D. F is not an immediate neighbour of B. Who sits at the centre?
P, Q, R and S are sitting on a bench and facing in the same direction. P sits next to Q but not next to R. S, who is sitting on the extreme right, does not sit next to either Q or R. How many of them each have two neighbors?
Five friends Ram, Priya, Raunak, Aditya and Shyam are sitting in a row facing north. Raunak is to the right of Shyam and Priya is to the left of Shyam but to the right of Rama. Raunak is to the left of Aditya. Who is fourth from the left end?
Six people P, Q, R, S, T and U sit in a row, not necessarily in the same order. If two persons sit in between P and Q, and two persons sit in between T and U, then how many persons sit in between R and S?
Six persons P, Q, R, S, T and U are sitting in a row facing north (not necessarily in the same order). Q sits fourth to the right of S. One person sits between P and Q. Three persons sit between R and T. R sits immediate left of P. How many persons sit between T and U?
