In the following questions, the symbols +, ×, =, ÷ and - are used with following meanings: 'P+Q' means 'P is greater than Q'.'P×Q' means 'P is either greater than or equal to Q'.'P=Q' means 'P is equal to Q'.'P÷Q' means 'P is smaller than Q'.'P-Q' means 'P is either smaller than or equal to Q'.Statements: S × Q, R + T, R - SConclusions: I. S + T II. Q = T
Options:
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 A
S ≥ Q -- (i); R > T -- (ii); R ≤ S -- (iii)From (ii) and (iii), we get D ≤ S ≥ R > T => No relationship between Q and T can be determined. Hence II is not true. But S > T. Hence, I is true.
