Question 121. P @ Q means P is neither greater than nor equal to Q.P # Q means P is not less than Q.P $ Q means P is neither greater than nor less than Q.P © Q means P is not greater than Q.P % Q means P is neither lesser than nor equal to Q.Statements: T $ X, X # W, W @ Y, Y % Z.Conclusions: I. T % W II. X @ Y III. Z % W
Answer: Option E. -> None follows
P @ Q => P < QP # Q => P ≥ QP $ Q => P = QP © Q => P ≤ QP % Q => P > Q
T $ X => T = X.X # W => X ≥ W.W @ Y => W < Y.Y % Z => Y ≥ Z.By combining the above statements we get,T = X ≥ W < Y > ZConclusion I: T % W => T > W, does not follow.Conclusion II: X @ Y => X < Y, does not follow.Conclusion III: Z % W => Z > W, does not follow.None follows.
Answer: Option D. -> if neither (I) nor (II) follows
a £ b means a ≤ ba $ b means a ≥ ba ↑ b means a < ba â— b means a > ba â–² b means a = bThe statement is (i) a $ b (ii) b * c (iii) c ↑ di.e, a ≥ b, b > c, c < d=> a ≥ b > c and d > c or c < dConclusion I: a â–² c => a = c is false.Hence, I does not follow.Conclusion II: b £ d => b ≤ d cannot be concluded.Hence, II does not follow.
Answer: Option B. -> if only conclusion (II) follows
a + b means a > b, a - b means a = b, a = b means a ≥ b, a * b means a ≤ b and a / b means a < b.According to the statementE / F => E < FF + G => F > GG - H => G = HConclusion (I): E + H => E > H, cannot be definitely determined.Conclusion (II): F + H => F > H, follows.
Question 124. p ۞ q means p is neither less than nor equal to q.p @ q means p is neither greater than nor equal to q.p # q means p is not less than q.p ∆ q means p is not greater than q.p □ q means p is neither smaller nor greater than q.Statement: s ۞ r, q # p, r ∆ pConclusions: I. q # r II. s ۞ q
Answer: Option A. -> if only conclusion (I) follows
p ۞ q means p > qp @ q means p < qp # q means p ≥ qp ∆ q means p ≤ qp □ q means p = qThe statement is (i) s ۞ r (ii) q # p (iii) r ∆ pFrom (i) s ۞ r => s > r(ii) q # p => q ≥ p or p ≤ q(iii) r ∆ p => r ≤ p or p ≥ r q ≥ p ≥ r and s > rConclusion I: q / r => q ≥ r is true.Hence, I follows.Conclusion II: s ۞ q => s > q cannot be concluded.Hence, II does not follow.
Answer: Option C. -> VIJ
There are two alphabetical series here. The first series is with the first letters only: STUVW. The second series involves the remaining letters: CD, EF, GH, IJ, KL.

Answer: Option A. -> JAK
The middle letters are static, so concentrate on the first and third letters. The series involves an alphabetical order with a reversal of the letters. The first letters are in alphabetical order: F, G, H, I , J. The second and fourth segments are reversals of the first and third segments. The missing segment begins with a new letter.

Answer: Option D. -> KLLA
The second and forth letters in the series, L and A, are static. The first and third letters consist of an alphabetical order beginning with the letter E.
The second and forth letters in the series, L and A, are static. The first and third letters consist of an alphabetical order beginning with the letter E.
Answer: Option C. -> ISS
The first letters are in alphabetical order with a letter skipped in between each segment: C, E, G, I, K. The second and third letters are repeated; they are also in order with a skipped letter: M, O, Q, S, U.

Answer: Option B. -> BC3D
Because the letters are the same, concentrate on the number series, which is a simple 2, 3, 4, 5, 6 series, and follows each letter in order.

Answer: Option B. -> NEO
This is an alternating series in alphabetical order. The middle letters follow the order ABCDE. The first and third letters are alphabetical beginning with J. The third letter is repeated as a first letter in each subsequent three-letter segment.
