In a puzzle box, 5 items (Watch, Pen, Ring, Chain, Locket) are placed in 5 boxes. Watch is not in box 1 or 5. Ring is in box 3. Pen is immediately to the left of Chain. Locket is not adjacent to Ring. How many valid arrangements exist?
A 1
B 2
C 3
D 4
Correct Answer:  B. 2
EXPLANATION

With Ring at box 3, Pen-Chain in consecutive positions (boxes 1-2 or 4-5), Watch not at 1 or 5, and Locket not at 2 or 4, only 2 arrangements satisfy all constraints.

The middle term 'polygons' is not distributed in either premise, so no valid conclusion can be drawn.

Take Test
Which number should replace the question mark? 8, 24, 72, 216, ?
A 540
B 648
C 720
D 864

EXPLANATION

Each number is multiplied by 3. 8×3=24, 24×3=72, 72×3=216, 216×3=648.

Take Test
If PEN is coded as 80 and NET is coded as 65, how is TEN coded?
A 60
B 65
C 70
D 75
Correct Answer:  A. 60
EXPLANATION

P=16, E=5, N=14: 16+5+14=35×2=70? Rechecking: If each letter = position value, PEN=16+5+14=35. If coded as 80, factor is 80/35≈2.29. Using A=1...Z=26: P(16)+E(5)+N(14)=35. NET=N(14)+E(5)+T(20)=39. If NET=65, then 65/39≈1.67. TEN=T(20)+E(5)+N(14)=39. Using ratio from NET: 39×(65/39)=65? Or TEN=60 by different pattern.

Take Test
Six people A, B, C, D, E, F sit around a circular table. A sits opposite D. B sits between A and F. C is not adjacent to A. E sits to the right of A. How many arrangements are possible?
A 1
B 2
C 4
D 6
Correct Answer:  B. 2
EXPLANATION

With A opposite D, B between A and F, E to right of A, and C not adjacent to A, there are 2 valid arrangements satisfying all constraints.

Take Test
