31. Study the following information carefully and answer the questions given below :

From the questions (31-34)
Seven people viz. A, B, C, D, E, F and G run different kilometres in a day. D runs more than B and E but less than G. B does not run the least. C runs more than B but less
than G and F. F runs more than G but not the most. The person who runs the second highest runs 17 km.

The person who runs the third lowest runs 8 km.
(Note : All the given numbers are whole numbers only).
If with respect to the number of kilometres run, F + B = 23 km and B + D = 19 km, then:
Which of the following is true as per the given information?
(A) C runs for 8 km.
(B) Only three people run less than D.
(C) The total number of kilometres run by C and A is definitely less than 24 km.

Correct Answer: (5) Bot (A) and (B)
Solution:

G > D > B, E
G, F > C > B
F > G
B does not run the least. F does not run the most.
Thus, E runs the least and A runs the most.

F + B = 23 km.
∴ B = (23 - 17) km. = 6 km.
B + D = 19 km.
∴ D = (19 - 6) km. = 13 km.
Therefore

Statement (C) is not true as
A + C = More than 25 km.
Statements (A) and (B) are true.

32. Study the above information carefully and answer the question.

How many people run more than A?

Correct Answer: (2) None, as A runs the highest
Solution:

G > D > B, E
G, F > C > B
F > G
B does not run the least. F does not run the most.
Thus, E runs the least and A runs the most.A runs the highest kilometres.

33. Study the above information carefully and answer the question.

If with respect to the number of kilometres run, F + B = 23 km, and B + D = 19 km, then
G possibly runs for ___ km in a day.

Correct Answer: (2) 15
Solution:

G > D > B, E
G, F > C > B
F > G
B does not run the least. F does not run the most.
Thus, E runs the least and A runs the most.
G runs 14, 15 or 16 kilometres.

34. How many such pairs of let- ters are there in the word GUARDIAN each of which has as many letters between them in the word (in both forward and backward directions) as they have between them in the English alphabetical order?

Correct Answer: (2) Three
Solution:

35.

If no such word can be formed, mark X as your answer. If more than one such word can be formed mark Z as your answer.

Correct Answer: (3) Z
Solution:

36. Study the following information carefully and answer the questions given below :

From the questions (36-40)
Eight people live on four different floors of a four storeyed building where the ground floor is numbered one, the one above that is numbered two and so on till the top- most floor of the building is numbered four. On each floor there are two flats viz. flat M and flat N such that flat M is exactly to the west of flat N. Also flat M of floor number two is immediately above flat M of floor number one. Similarly, flat N of floor number three is immediately above flat N of floor number two and so on. Thus, only two people live on each floor and only one person lives in each flat. Also each one of them is of a different age.
A lives on an odd numbered floor in the flat immediately below the one in which the 69 year old lives. No one lives to the west of A. There is only one floor between the floors on which the 69 year old and the 53 year old live. The 47 year old lives exactly to the west of the 53 year old. B lives in the flat immediately below the flat in which the 47 year old lives. The one who live exactly to the east of B is 24 years old. There is only one floor between the floors on which C and the 24 year old lives. G lives exactly to the east of E. G is not 53 years old. G is 6 years elder than E. H lives exactly to the east of F. The sum of the present ages of F and C is 109. C lives on one of the floors above F. The difference between the present ages of C and A is 7. D is 12 years younger than the one who lives exactly to his west.
Who amongst the following is 55 years old?

Correct Answer: (1) A
Solution:
Floor NumberMN
FourE 69 yearsG 75 years
ThirdA 55 yearsC 62 years
SecondF 47 yearsH 53 years
FirstB 36 yearsD 24 years

C - A = 7 years
∴ A = (62 - 7) years
= 55 years
[Note : A = C + 7 is not possible as each person is of a different age]
F + C = 109 years
∴ C = (109 - 47) years
= 62 years
B = (D + 12) years
= 36 years
A is 55 years old.

37. Study the above information carefully and answer the question.

Which of the following represents the floor number and the flat in which D lives?

Correct Answer: (4) Floor number 1, flat N
Solution:C - A = 7 years
∴ A = (62 - 7) years
= 55 years
[Note : A = C + 7 is not possible as each person is of a different age]
F + C = 109 years
∴ C = (109 - 47) years
= 62 years
B = (D + 12) years
= 36 years
D lives on Floor number 1, Flat N.

38. Study the above information carefully and answer the question.

Which of the following combinations is not correct as per the given information?

Correct Answer: (3) G-the 62 year old
Solution:C - A = 7 years
∴ A = (62 - 7) years
= 55 years
[Note : A = C + 7 is not possible as each person is of a different age]
F + C = 109 years
∴ C = (109 - 47) years
= 62 years
B = (D + 12) years
= 36 years
G is 75 years old.

39. Study the above information carefully and answer the question.

Which of the following statements is true as per the given information?
(A) D is 45 years younger than E.
(B) The sum of the present ages of H and B is 89 years.
(C) The 55 year old lives on one of the floors below D.
(D) G is younger than H.

Correct Answer: (5) Both (A) and (B)
Solution:C - A = 7 years
∴ A = (62 - 7) years
= 55 years
[Note : A = C + 7 is not possible as each person is of a different age]
F + C = 109 years
∴ C = (109 - 47) years
= 62 years
B = (D + 12) years
= 36 years
E - D = (69 - 24) years
= 45 years
(A) is true.
H + B = (53 + 36) years
= 89 years
(B) is true.
A is 55 years old. A lives on one of the floors above D.
Therefore, (C) is not true.
G (75 years) is older than H (53 years).
Therefore, (D) is not true.

40. Study the above information carefully and answer the question.

What is the difference between the present ages of H and E? (in years)

Correct Answer: (2) 16
Solution:C - A = 7 years
∴ A = (62 - 7) years
= 55 years
[Note : A = C + 7 is not possible as each person is of a different age]
F + C = 109 years
∴ C = (109 - 47) years
= 62 years
B = (D + 12) years
= 36 years
E - H = (69 - 53) years
= 16 years
