Q.23Hard
In a coding system, vowels are replaced by the next consonant and consonants by the next vowel. How is LOGIC coded?
6 boxes are arranged in a row. Box 2 is heavier than Box 1. Box 4 is lighter than Box 3. Box 5 is heavier than Box 6. If Box 3 is heavier than all others, which box is the lightest?
Answer: C
While we know Box 4 < Box 3 and Box 6 < Box 5, we cannot definitively compare Box 1, 2, 4, and 6 to determine the lightest.
Q.25Hard
In a complex arrangement, 9 boxes are placed in 3 rows and 3 columns. Box at position (1,2) contains Red balls. Position (2,3) contains Green balls. Position (3,1) contains Blue balls. If you need to place Yellow balls such that no two colors share a row or column, where should Yellow go?
Answer: A
Red at (1,2) blocks row 1 and column 2. Green at (2,3) blocks row 2 and column 3. Blue at (3,1) blocks row 3 and column 1. Yellow must avoid: rows 1,2,3 and columns 1,2,3 - impossible for standard placement, but (2,1) conflicts with Blue's column 1. Rechecking: (1,3) at row 1 conflicts with Red's row. (2,1) at column 1 conflicts with Blue's column. Best option avoiding maximum conflicts: (2,1).

Q.26Hard
Eight boxes labeled 1-8 are arranged in a line. Box 3 is between boxes 2 and 4. Box 5 is immediately right of box 4. Box 8 is immediately left of box 1. What is the arrangement?
Answer: D
The constraints 'Box 3 between 2&4' and 'Box 5 right of Box 4' and 'Box 8 left of Box 1' create conflicting arrangements in a linear sequence. Box 8 cannot be immediately left of Box 1 in a line where boxes are numbered sequentially.
Q.27Hard
A woman's son's mother's father's only daughter is the woman herself. What is the relation?
Answer: A
Woman → Son's mother = Woman. Woman's father = Boy's grandfather. Grandfather's only daughter = Woman. This is logically consistent - she is indeed her son's mother and her father's only daughter.
Q.28Hard
In a circular arrangement of 8 people, P is opposite to T. Q is third to the right of P. R is second to the left of T. Who is sitting between R and Q (going clockwise from R)?
Answer: C
With 8 people in circle, opposite means 4 seats apart. If P at position 1, T at position 5. Q third right of P: position 4. R second left of T: position 3. Between R(3) and Q(4) going clockwise: nobody directly, but without complete arrangement, exact answer cannot be determined uniquely.
