Linear Sequencing

Introduction • Linear fashion means arrangement in a row. • Analyze the problem and arrange it. • Find the direct condition and start to solve, because the remaining conditions are based on the direct condition. • No condition for the particular item, shows their is possibility in answer.

Problem 1 There are five persons(A,B,C,D,E) in a room seated in a single row in the following manner: A does not sit immediately next to E. E and D sit immediately next to each other. C is at the extreme right end of the row. A is to the immediate left of C. Who must sit in the middle seat of the row?

Linear sequencing • Answer: • Middle Seat : B or D

Problem 2 M,N,O,P,Q,R,S,T,U,V,W are 11 persons in a team. O is their captain who makes them sit in a row. P and R sit together and so do V and W . Whereas there are exactly four seats in between these pairs. T and U sit together with T to the immediate right of S, who is next to Q. M and N sit in the same order at one extreme with no one to the left of_P. Cont…

Problem 2 1.Who sits at fourth place? 2.How many persons sit in between S and N? 3.How many ways of arrangements are possible? 4. Show the arrangements possible?

Linear Sequencing • Answers: • The fourth term is S • There are 6 persons between S and N • There are 2 ways of arranging. • The arrangement possible, • P R Q S T U V W O M N (or) • P R Q S T U W V O M N

Problem 3 Raji and her three friends were to be photographed. Mansi was to the left of Amrita, Manju was to the right of Amrita. Raji was between Manju and Amrita. Who was second from left in the picture?

Linear sequencing Answer: Amrita was second from the left

Problem 4 Six persons A, B, C, D, E and F are standing in a row. B is between F and D, E is between A and C. A does not stand next to either F or D. C does not stand next to D. F is between which of the following pair of persons? i) C & B ii) C & D iii) A & C iv) A & B

Linear Sequencing Answer: i) C & B

Problem 5 Asha, Babita, Chinni, Deepa, Kavitha and Fatima are standing in a row. Babita is between Fatima and Deepa. Kavitha is between Asha and Chinni. Asha does not stand next to either Fatima or Deepa. Fatima is between which of the pair of persons?
