Directions (Q. 1-5): Study the following information to answer the given questions:
There are 8 people in a family – P, Q, R, S, T, U, V and W are sitting around a circle facing the centre but not necessarily in the same order. All people have relation with other people.
Q sits second to left of W’s husband. No female is an immediate neighbor of Q. S’s daughter sits second to right of U. U is the sister of V. U is not an immediate neighbor of W’s husband.
Only one person sits between P and U. P is the father of V. W’s brother S sits to the immediate left of W’s mother. Only one person sits between W’s mother and T. Only one person sits between W and V. V is the mother of R. V is not an immediate neighbor of T.

Arrangement

Explanation:
First try to make the relationship among all people.12-1
As seen in figure, we get 2 diagrams. Since all people have relationship with one another, in this P can be W’s husband only.
And since given that only one person sits between W’s mother and T, this means W’s mother is not T, so S’s daughter is T. This gives12-2
Now make the seating arrangement diagram.12-3

Directions (Q. 6-10): In the following questions, the symbols * , $, #, δ and % are used with the following meaning as illustrated below:
‘P $ Q’ means ‘P is neither greater than nor smaller than Q’.
‘P δ Q’ means ‘P is neither greater than nor equal to Q’.
‘P % Q’ means ‘P is neither smaller than nor equal to Q’.
‘P*Q’ means ‘P is not smaller than Q’.
‘P # Q’ means ‘P is not greater than Q’.
Now in each of the following question assuming the given statements to be true, find which of the conclusions I, II, III and IV given below them is/are definitely true and give your answer accordingly.

  1. Statements: D * K, K % T, T δ R, R # M
    Conclusions:
    I. M % T
    II. D %T
    III.R % K
    IV.M # D
    A) Only I is true
    B) Only II is true
    C) Only I and II are true
    D) Only II and III are true
    E) None of these
    Answer & Explanation

    Explanation:
    D ≥ K > T < R ≤ M
  2. Statements: F δ W, W $ V, V % B, B * D
    Conclusions:
    I. F δ B
    II. D δ V
    III. V % F
    IV. W%D
    A) Only I is true
    B) Only I, II and III are true
    C) Only I, II and IV are true
    D) Only II, III and IV are true
    E) None of these
    Answer & Explanation
    D) Only II, III and IV are true

    Explanation:
    F < W = V > B ≥ D
  3. Statements : Z % N, N # K, K $ M, M δ R
    Conclusions:
    I. M $ N
    II. M % N
    III.R % N
    IV. Z % M
    A) Only either I or II and III are true
    B) Only either I or II is true
    C) Only either I or II and III and IV are true
    D) Only III is true
    E) None of these
    Answer & Explanation
    A) Only either I or II and III are true

    Explanation:
    Z > N ≤ K = M < R N ≤ K = M gives either M = N or M > N
  4. Statements : F # K, K $ T, D % T, V * D
    Conclusions:
    I. T * F
    II. D % K
    III. D % F
    IV. V % K

    C) Only II and III are true
    D) Only II, III and IV are true
    E) All are true
    Answer & Explanation
    E) All are true

    Explanation:
    F ≤ K = T < D ≤ V gives all conclusions as true
  5. Statements : H $ J, J δ Y, Y * K, K # W
    Conclusions:
    I. W % Y
