Question 61. In these questions, certain symbols have been used to indicate relationships between elements follows:'A*B' means 'A is either equal to or greater than B'.'A$B' means 'A is equal to B'.'A£B' means 'A is either equal to or smaller than B'.'A&B' means 'A is smaller than B'.'A@B' means 'A is greater than B'.Statements: Y $ Z, H $ D, Z * DConclusions: 1. D £ Y II. H £ Z
Answer: Option E. -> if both the conclusions I and II are true.
Combining all three statements, we get Y = Z ≥ D = H. Therefore D ≤ Y and H ≤ Z are true.
Question 62. In these questions, certain symbols have been used to indicate relationships between elements follows:'A*B' means 'A is either equal to or greater than B'.'A$B' means 'A is equal to B'.'A£B' means 'A is either equal to or smaller than B'.'A&B' means 'A is smaller than B'.'A@B' means 'A is greater than B'.Statements: M @ N, P @ R, P & NConclusions: I. P £ M II. R & N
Answer: Option B. -> if only conclusion II is true.
Combining all the three statements together, we get M > N > P > R. Therefore P ≤ M is not true, but R < N is true.
Question 63. In these questions, certain symbols have been used to indicate relationships between elements follows:'A*B' means 'A is either equal to or greater than B'.'A$B' means 'A is equal to B'.'A£B' means 'A is either equal to or smaller than B'.'A&B' means 'A is smaller than B'.'A@B' means 'A is greater than B'.Statements: T & K, K * B, S * KConclusions: I. B * T II. S £ T
Answer: Option D. -> if neither conclusion I nor II is true.
Combining I and III, we get S ≥ K > T. Therefore S ≤ T is not true. We have no information about the relationship between B and T.
Question 64. In these questions, certain symbols have been used to indicate relationships between elements follows:'A*B' means 'A is either equal to or greater than B'.'A$B' means 'A is equal to B'.'A£B' means 'A is either equal to or smaller than B'.'A&B' means 'A is smaller than B'.'A@B' means 'A is greater than B'.Statements: P @ R, M @ N, P & NConclusions: I. N @ R II. P & M
Answer: Option E. -> if both the conclusions I and II are true.
Combining all the three statements, we get M > N > P > R. Therefore N > R and P < M are true.
Question 65. In the following questions the symbols *, ×, $, @ and + are used with the following meaning:'P×Q' means 'P is neither smaller nor greater than Q'.'P@R' means 'P is neither equal to nor greater than Q'.'P*Q' means 'P is either equal to or smaller than Q'.'P+Q' means 'P is neither equal to nor smaller than Q'.Statements: D * F, F $ M, M @ KConclusions: I. F @ K II. D @ K
Answer: Option D. -> if neither conclusion I nor II is true.
-NA-
Question 66. In the following questions the symbols *, ×, $, @ and + are used with the following meaning:'P×Q' means 'P is neither smaller nor greater than Q'.'P@R' means 'P is neither equal to nor greater than Q'.'P*Q' means 'P is either equal to or smaller than Q'.'P+Q' means 'P is neither equal to nor smaller than Q'.Statements: K + M, M * R, R × TConclusions; I. K + T II. T + M
Answer: Option B. -> if only conclusion II is true.
-NA-
Question 67. In the following questions the symbols *, ×, $, @ and + are used with the following meaning:'P×Q' means 'P is neither smaller nor greater than Q'.'P@R' means 'P is neither equal to nor greater than Q'.'P*Q' means 'P is either equal to or smaller than Q'.'P+Q' means 'P is neither equal to nor smaller than Q'.Statements: T @ M, M * R, R × NConclusions: I. M × N II. M @ N
Answer: Option C. -> if either conclusion I or II is true.
-NA-
Question 68. In the following questions the symbols *, ×, $, @ and + are used with the following meaning:'P×Q' means 'P is neither smaller nor greater than Q'.'P@R' means 'P is neither equal to nor greater than Q'.'P*Q' means 'P is either equal to or smaller than Q'.'P+Q' means 'P is neither equal to nor smaller than Q'.Statements: B $ N, N × R, R + TConclusions: I. B $ R II. T @ N
Answer: Option E. -> if both the conclusions I and II are true.
-NA-
Question 69. In the following questions the symbols *, ×, $, @ and + are used with the following meaning:'P×Q' means 'P is neither smaller nor greater than Q'.'P@R' means 'P is neither equal to nor greater than Q'.'P*Q' means 'P is either equal to or smaller than Q'.'P+Q' means 'P is neither equal to nor smaller than Q'.Statements: N × P, K + P, Q @ KConclusions; I. K + N II. Q + N
Answer: Option A. -> if only conclusion I is true.
-NA-
Question 70. In the following questions the symbols +, ×, ?, @ and $ are used with the following meanings:'P+Q' means 'P is neither smaller nor greater than Q'.'P×Q' means 'P is neither equal to nor smaller than Q'.'P?Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than or equal to Q'.'P$Q' means 'P is not equal to Q'.Statements: A + B, B $ C, C ? AConclusions: I. C $ A II. B + C
Answer: Option A. -> if only conclusion I is true.
A = B -- (i); B ≠C -- (ii); C < A -- (iii)From (iii), conclusion I is true. II contradicts statement (ii). Hence it is not true.
