  • Question 1/15
    1 / -0

    Direction: In the following question assuming the given statements to be True, find which of the conclusion among given conclusions is/are definitely true and then give your answers accordingly.

    On Combining:O > A > L ≥ P > R; O > A > L < M

    Conclusions:

    I. M ≤ O → False (As, O > A > L < M → Clear relation between M and O cannot be determined)

    II. R  > A → False (As, L ≥ P > R)

    Hence, none of the conclusion follows.

  • Question 4/15
    1 / -0

    Which of the following symbols should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression in such a manner that “W > R” definitely holds true?

    S ___ W ___ P ___ R

    Solutions

    Let us check each option:

    1) S < W = P < R → W < R

    2) S ≥ W ≤ P > R → relation between W and R can’t be determined.

    3) S ≥ W > P = R → W > R

    4) S = W < P > R → relation between W and R can’t be determined.

    Hence, the correct sequence of symbols to satisfy the given condition is “≥, >, =”.

    2) F, G, C → F > G ≥ B ≥ D ≤ E < C (This gives D < C)

    3) C, G, F → C > G ≥ B ≥ D ≤ E < F (This gives C > D)

    Hence, either 2) or 3) makes ‘C > D’ definitely true.

  • Question 11/15
    1 / -0

    Directions: In these questions, relationships between different elements are shown in the statements. These statements are followed by some conclusions.

    Give answer-

    Statement: M < R = Q < N > C, N < H < T
