  1. In the following questions the symbols @, +, ©, $, ? and ? are used with the following meaning:
    'P?Q' means 'P is not equal to Q'.
    'P@Q' means 'P is greater than Q'.
    'P+Q' means 'P is smaller than Q'.
    'P©Q' means 'P is either greater than or equal to Q'.
    'P$Q' means 'P is either smaller than or equal to Q'.
    'P?Q' means 'P is equal to Q'.
    Now each of the following questions assuming the given statements to be true, find which of the two conclusions I and II given them is/are definitely true. Give answer.

    Statements: B + D, D @ N, N $ H
    Conclusions: I. H © D   II. H © N
    2. A.
    if only conclusion I is true.
    B.
    if only conclusion II is true.
    C.
    if either conclusion I or II is true.
    D.
    if neither conclusion I nor II is true.
    E.
    if both the conclusions I and II are true.

    Answer : Option B

    Explanation :

    B < D -- (i); D > N -- (ii); N â‰¤ H -- (iii)

    From equations (ii) and (iii), we can't obtained any specific relation between H and D. Hence, conclusion I (H â‰¥ D) is not true. But conclusion II (H â‰¥ N) follows from equation (iii).
