Question 5
Six people sit in a row. Initially, they are in some order. First, the persons at positions 1 and 2 swap places. Next, the persons at positions 4 and 6 swap places. After these swaps, who sits immediately to the right of C?
Final order after swaps is: G E C F B D. C is at position 3; the person to the right is F.
Question 6
Six people D, B, C, A, E, F live in a 6-floor building (1=ground, 6=top). F lives on floor 5. E lives on floor 4. C lives above E but below F. Who lives on the top floor?
Based on the clues, A is on the top floor (floor 6).
Question 7
Six people A, D, E, F, B, C live in a 6-floor building (1=ground, 6=top). D lives above everyone else. F lives below everyone else. B lives above C. Who lives on the top floor?
Based on the clues, D is on the top floor (floor 6).
Question 8
In a queue of 55 people, Ram is 15th from the left and Sita is 15th from the right. There is an odd number of people between them. Gita stands exactly in the middle of Ram and Sita. What is Gita's rank from the right?
Seven people A, B, C, D, E, F, G stand in a row facing North. i) A is two places to the left of C. ii) D is two places to the right of C. iii) B stands somewhere between A and D. iv) E is not at the extreme left and F is not at the extreme right. Who stands at the extreme left?
From clues i and ii, positions are: X _ Z _ Y (positions 1,3,5 or 2,4,6 or 3,5,7). Clue iii places W between X and Y. Clue iv eliminates positions 3,5,7 for left end. Therefore, X must be at position 1 (extreme left).
Question 10
Six students R, U, S, P, T, V took a test. T scored higher than S. S scored higher than U. U scored higher than P. P scored higher than V. Who ranked 3rd?
From the comparative scores, the descending order is: T > S > U > P > V > R. Hence, 3rd is U.
Question 11
Five friends—P, Q, R, S, and T—are compared based on their height. i) P is taller than T. ii) R is shorter than T. iii) S is shorter than Q. iv) Q is shorter than R. Who is the third tallest among them?
Combine the height comparisons: 1. P > T 2. T > R 3. R > Q 4. Q > S Thus, the order is P > T > R > Q > S. Third tallest is R.
Question 12
Six people sit in a row. Initially, they are in some order. First, the persons at positions 1 and 2 swap places. Next, the persons at positions 4 and 6 swap places. After these swaps, who sits immediately to the right of A?
Final order after swaps is: E B A C F G. A is at position 3; the person to the right is C.
Question 13
Five people I, H, J, F, and G are compared by Height and Age. i) F is older than J but shorter than H. ii) I is the tallest, but not the oldest. iii) G is older than I. iv) J is not the shortest, and H is the youngest. Who are the oldest and the shortest respectively?
Age: From (iii) J > F, and (ii) says F is not oldest, so J is oldest. Clue (iv) sets G as youngest. Also (i) gives I > H. A valid age order is G > I > F > J > H. Height: (ii) makes F tallest; (i) ensures G taller than I; (iv) H not shortest. A valid height order is I > J > H > F > G. Thus, oldest is G and shortest is G.
Question 14
Six people sit in a row. Initially, they are in some order. First, the persons at positions 1 and 2 swap places. Next, the persons at positions 4 and 6 swap places. After these swaps, who sits immediately to the right of E?
Final order after swaps is: A G E F D C. E is at position 3; the person to the right is F.
Question 15
For a project: Draft before Revise; Revise before Submit; Research before Draft. If all events happen sequentially with no gaps, what is the total minimum time? (Durations: {'Research': 120, 'Draft': 180, 'Revise': 90, 'Submit': 30, 'Publish': 60})
Event order: Research → Draft → Revise → Submit → Publish. Total time = 480 minutes.
Question 16

Question 18
In the family tree, Elizabeth is the mother of Henry. Lucas is the son of Henry and Margaret. What is the relation between Elizabeth and Lucas?
Tracing the family tree: William → Henry → Lucas. Therefore, William is the grandfather of Lucas. In family hierarchy, grandparents are two generations above grandchildren.

Question 20
Five people G, H, I, J, and F are compared by Height and Age. i) J is older than I but shorter than H. ii) G is the tallest, but not the oldest. iii) F is older than G. iv) I is not the shortest, and H is the youngest. Who are the oldest and the shortest respectively?
Age: From (iii) J > F, and (ii) says F is not oldest, so J is oldest. Clue (iv) sets G as youngest. Also (i) gives I > H. A valid age order is F > G > J > I > H. Height: (ii) makes F tallest; (i) ensures G taller than I; (iv) H not shortest. A valid height order is G > I > H > J > F. Thus, oldest is F and shortest is F.
