P `alpha` Q means P is greater than Q.
P `beta` Q means P is either greater than or equal to Q.
P `gamma` Q means P is equal to Q.
`delta` Q means P is smaller than Q.
`eta` Q means P is either smaller than or equal to Q.
Statemens: `P gamma O, R alpha T, S eta P, R delta O`
Conclusions: I. `S gamma O` II. `P delta T`

Options

A. If only I is true
B. if only conclusion II is true
C. if either conclusion I or II is true
D. if either I nor II is true

Answer

D

Explanation

Statements: `P = O, R gt T, S le P, R O`
Conclusions: I. S = O II. `P lt T`
I is wrong (Tip 7: quick method) as given statements contain no equalities have S. II must be wrong as T is not greater than any term in the given inequalities. (Tip 8(ii): quick method)
