Worksheet 20 of 30 (66% complete)
Question 1
Six students R, S, T, V, Q, U took a test. Q scored higher than R. R scored higher than U. U scored higher than T. T scored higher than V. Who ranked 3rd?
From the comparative scores, the descending order is: Q > R > U > T > V > S. Hence, 3rd is U.
Question 2
Five friends A, B, C, D, and E are standing in a single row facing North. i) A is exactly in the middle of the row. ii) D is not at any end. iii) E is to the immediate left of C. iv) B is at one of the ends. v) D is to the immediate right of A. Who is standing at the left end?
From (i), A is at position 3. From (v), D must be at position 4. (iii) places E and C as consecutive with E left of C at positions 1 and 2. (iv) puts B at the remaining end, position 5. Final order: E C A D B. Left end is E.
Question 3
For a project: Shower before Breakfast; Wake Up before Shower; Breakfast before Commute. If all events happen sequentially with no gaps, what is the total minimum time? (Durations: {'Wake Up': 10, 'Shower': 15, 'Breakfast': 20, 'Commute': 45, 'Work Start': 0})
Event order: Wake Up → Shower → Breakfast → Commute → Work Start. Total time = 90 minutes.
Question 4
Six people B, C, A, E, F, D live in a 6-floor building (1=ground, 6=top). B lives above C. E lives below D. Who lives on the top floor?
Based on the clues, B is on the top floor (floor 6).
Question 5
For a project: Wake Up before Shower; Breakfast before Commute; Shower before Breakfast. If all events happen sequentially with no gaps, what is the total minimum time? (Durations: {'Wake Up': 10, 'Shower': 15, 'Breakfast': 20, 'Commute': 45, 'Work Start': 0})
Event order: Wake Up → Shower → Breakfast → Commute → Work Start. Total time = 90 minutes.
Question 6
In a queue of 40 people, Ram is 10th from the left and Sita is 11th 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?
In the family tree, Eleanor is the mother of Charles. George is the son of Charles and Victoria. What is the relation between Eleanor and George?
Tracing the family tree: Thomas → Charles → George. Therefore, Thomas is the grandfather of George. In family hierarchy, grandparents are two generations above grandchildren.
Question 8
Six students P, T, S, V, Q, R took a test. V scored higher than S. S scored higher than Q. Q scored higher than T. T scored higher than P. Who ranked 3rd?
From the comparative scores, the descending order is: V > S > Q > T > P > R. Hence, 3rd is Q.
Question 9
In a queue of 52 people, Ram is 13th from the left and Sita is 10th 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?
For a project: Breakfast before Commute; Shower before Breakfast; Wake Up before Shower. If all events happen sequentially with no gaps, what is the total minimum time? (Durations: {'Wake Up': 10, 'Shower': 15, 'Breakfast': 20, 'Commute': 45, 'Work Start': 0})
Event order: Wake Up → Shower → Breakfast → Commute → Work Start. Total time = 90 minutes.
Question 11
Among Y, Q, T, P, W, R, V, the following comparisons are known: R is faster compared to T. T is faster compared to Y. Y is faster compared to P. P is faster compared to V. V is faster compared to Q. Q is faster compared to W. Who is the middle?
Chain of comparisons: R > T > Y > P > V > Q > W. Therefore, the middle is P.
Question 12
In a queue of 48 people, Ram is 15th from the left and Sita is 10th 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?
Among X, P, T, U, the following comparisons are known: U is taller when compared with T. T is taller when compared with P. P is taller when compared with X. Who is the shortest?
Chain of comparisons: U > T > P > X. Therefore, the shortest is X.
Question 14
Five people H, I, F, G, and J are compared by Height and Age. i) G is older than F but shorter than I. ii) H is the tallest, but not the oldest. iii) J is older than H. iv) F is not the shortest, and I 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 J > H > G > F > I. Height: (ii) makes F tallest; (i) ensures G taller than I; (iv) H not shortest. A valid height order is H > F > I > G > J. Thus, oldest is J and shortest is J.
Question 15
Seven students B, G, F, H, C, A, D took an exam. H and C are tied at rank 2. B and A are tied at rank 4. What is the rank of F?
The ranking distribution is: G(1), H(2), C(2), D(3), B(4)... two tied for 2nd, two tied for 4th. 5 is the correct answer.
Question 16
Seven students G, H, I, D, C, A, B took an exam. H, D and B are tied at rank 1. What is the rank of A?
The ranking distribution is: H(1), D(1), B(1), G(2), I(3)... three tied for 1st. 5 is the correct answer.
Question 17
For a project: Breakfast before Meeting; Lunch before Presentation; Meeting before Lunch. If all events happen sequentially with no gaps, what is the total minimum time? (Durations: {'Breakfast': 30, 'Meeting': 60, 'Lunch': 45, 'Presentation': 90, 'Review': 60})
Event order: Breakfast → Meeting → Lunch → Presentation → Review. Total time = 285 minutes.
Question 18
In a queue of 47 people, Ram is 14th from the left and Sita is 14th 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?
For a project: Shower before Breakfast; Breakfast before Commute; Wake Up before Shower. What is the earliest possible start time for Work Start if Wake Up starts at time 0?
Event order: Wake Up → Shower → Breakfast → Commute → Work Start. Total time = 90 minutes.
Question 20
Among Q, U, Z, X, R, the following comparisons are known: X is older compared to Q. Q is older compared to Z. Z is older compared to U. U is older compared to R. Who is the middle?
Chain of comparisons: X > Q > Z > U > R. Therefore, the middle is Z.
