Question
Statements: B ≤ I; E = D; H > F; C ≤ H; I = D;
A ≤ B; H < E Conclusions: (i) I > F (ii) B ≤ H (iii) A ≤ E (iv) E > F 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.Solution
Given statements: B ≤ I; E = D; H > F; C ≤ H; I = D; A ≤ B; H < E On combining: A ≤ B ≤ I =D = E > H ≥ C ; H > F Conclusions: (i) I > F , True since I= D = E > H > F (ii) B ≤ H , False since either B ≤ H or B > H (iii) A ≤ E , True since A ≤ B ≤ E (iv) E > F , True since E > H > F Hence, option 2 is the answer.
