In a logic puzzle with 4 people and 4 attributes, if person A has attribute 1, person B doesn't have attribute 1, and persons C and D share attribute 1, then how many people have attribute 1?
A1
B2
C3
D4
Correct Answer: C. 3
Explanation:
Person A has attribute 1 (count: 1). B doesn't have it (count: 1). C and D both have it (count: 1 + 2 = 3). Total: 3 people have attribute 1.
In a row of 8 people, A sits 3rd from left. B sits 5 positions to the right of A. What is B's position from the right?
A2nd
B3rd
C4th
D5th
Correct Answer: A. 2nd
Explanation:
A is 3rd from left, so B is at position 3+5=8. From right, 8th position = 1st from right. Wait, recalculating: A at 3rd, B at 8th from left means B is at 8-8+1=1st from right. Actually 9-8=1st from right.
