Question
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: K © M, M ∆ R, R ? T Conclusions: I. K © T II. M ? T
Answer: Option D Combining all the equations, we getK ≥ M ≠R = T => M ≠TFrom this we can't get any specific relation between K and T. Hence, conclusion I is not true. Conclusion II is false since M ≠T.
