Question 121. In the following questions, the symbols, #, @, $, © and % are used with the following meaning as illustrated below:'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than nor smaller than Q'.'P$Q' means 'P is not smaller than Q'.'P©Q' means 'P is neither smaller than nor equal to Q'.Statements: J % V, V # T, T © RConclusions: I. R @ J II. R # J
Answer: Option D. -> if neither conclusion I nor II is true.
J ≤ V -- (i); V < T -- (ii); T > R -- (iii)combining (i) and (ii), we getT > V ≥ J -- (iv)From (iii) and (iv) we do not get any specific relation between R and J. Hence, neither conclusion I nor conclusion II is necessarily true.
Question 122. In the following questions, the symbols, #, @, $, © and % are used with the following meaning as illustrated below:'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than nor smaller than Q'.'P$Q' means 'P is not smaller than Q'.'P©Q' means 'P is neither smaller than nor equal to Q'.Statements: K @ W, B % W, N # BConclusions: I. K @ N II. N # K
Answer: Option B. -> if only conclusion II is true.
K = W -- (i); B ≤ W -- (ii); N < B -- (iii)combining all, we getK = W ≥ B > N => K > N=> N > K (conclusion II).Hence, conclusion I is not true but conclusion II is true.
Question 123. In the following questions, the symbols, #, @, $, © and % are used with the following meaning as illustrated below:'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than nor smaller than Q'.'P$Q' means 'P is not smaller than Q'.'P©Q' means 'P is neither smaller than nor equal to Q'.Statements: D @ K, K $F, H # FConclusions: I. H # D II. D © F
Answer: Option A. -> if only conclusion I is true.
D = K -- (i); K ≥ F -- (ii); H < F -- (iii) combining all, we get:D = K ≥ F > H => D > H and D > F.
Question 124. In the following questions, the symbols, #, @, $, © and % are used with the following meaning as illustrated below:'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than nor smaller than Q'.'P$Q' means 'P is not smaller than Q'.'P©Q' means 'P is neither smaller than nor equal to Q'.Statements: M © R, R % T, T @ NConclusions: I. N © R II. N @ R
Answer: Option C. -> if either conclusion I or II is true.
M > R -- (i); R ≤ T -- (ii); T = N -- (iii)Combining (ii) and (iii), we getT = N ≥ R => N > R (conclusion I) or N = R (conclusion II).
Question 125. In the following questions, the symbols, #, @, $, © and % are used with the following meaning as illustrated below:'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is neither greater than nor smaller than Q'.'P$Q' means 'P is not smaller than Q'.'P©Q' means 'P is neither smaller than nor equal to Q'.Statements: R © E, D @ E, M $ DConclusions: I. D # R II. E @ R
Answer: Option A. -> if only conclusion I is true.
R > E -- (i); D = E -- (ii); M ≥ D -- (iii)R > E = D => R > D and R. E=> D < R (conclusion I) and E < R.
Answer: Option E. -> None of these
-NA-

-NA-
Question 130. In the following given below, certain symbols are used with the following meanings:'P$Q' means 'P is neither equal to nor smaller than Q'.'P©Q' means 'P is not smaller than Q'.'P*Q' means 'P is neither greater nor smaller than Q'.'P#Q' means 'P is neither greater than nor equal to Q'.'P@Q' means 'P is not greater than Q'.Statements: Q # P, P @ F, F * MConclusions: I. M $ P II. P * M
Answer: Option C. -> if either conclusion I or II is true.
Q < P -- (i); P ≤ F -- (ii); F = M -- (iii)Combining all the equations, we getF = M ≥ P > Q => M > P, i.e M > P or M = P.Hence, either conclusion I or II is true.
