The positions of the first and fifth letters of the word SUITABLE are interchanged. Similarly, the positions of second and sixth letters, third and seventh letters and fourth and eighth letters are interchanged. In the new arrangement, how many letters are there in the English alphabetical series between the alphabet which is third from the left end, and the alphabet which is second from the right end?
Correct Answer
C. Two
Explanation
In the new arrangement, the word SUITABLE becomes AETIBULS. The alphabet which is third from the left end is C, and the alphabet which is second from the right end is Y. There are two letters in the English alphabetical series between C and Y, which are D and E. Therefore, the answer is Two.

Read the following information carefully and answer the question which follows.
Among A, B, C, D, and E, each scored different marks in an examination. Only one person scored more than C. E scored more than a but less than D. D did not score the highest marks. The one who scored the second-lowest scored 71 % marks. C scored 92% marks.
Who among the following is most likely to have scored 87% marks?
Correct Answer
E. Either A or D
Explanation
Let's analyze the given information step-by-step:
C's high score: C scored 92%, and only one person scored higher. This means C is in second place.
D's position: E scored less than D, and D did not score the highest. This puts D somewhere in the middle ranks.
E's position: E scored more than A but less than D, placing E in the lower-middle range.
Second-lowest score: The second-lowest score was 71%, which must belong to A, as E scored higher.
Considering these points, the scores might look like this (from highest to lowest):
Unknown (highest scorer)
C (92%)
D (somewhere below C)
E (below D)
A (71%)
Since 87% falls within the range where D could be, it's possible D scored those marks. It's also possible that the unknown highest scorer got a very high percentage, pushing D lower and allowing A to achieve 87%.
Therefore, either A or D could have scored 87%.

'HC' is related to 'KQ' in a certain way. Similarly, ‘OG’ is related to 'AB' in the same way. To which of the following is 'RK' related, following the same pattern?
Correct Answer
A. TJ
Explanation
The given alphabetical series can be rearranged as follows: A B C D E F G H I J K L M N O P Q R S T U V. Each pair of letters in the related terms is separated by one letter in the series. For example, in the given pair 'HC' and 'KQ', the letters 'H' and 'K' are separated by one letter 'I' in the series, and the letters 'C' and 'Q' are also separated by one letter 'D' in the series. Applying the same pattern, the letters 'R' and 'T' are separated by one letter 'S' in the series. Therefore, 'RK' is related to 'TJ'.

How many brothers does Meghna have? Meghna is a girl.
I. Kishore, the father of Meghna, is the only child of Kamal. Kamal has only two grandchildren.
II. Jyoti, the daughter-in-law of Kamal, has a son and a daughter.
Correct Answer
E. If the data in both the statements I and II together are necessary to answer the question
Explanation
Statement I alone tells us that Meghna is the only child of Kishore, who is the only child of Kamal. Kamal has two grandchildren, but we don't know if they are Meghna's siblings or not. Therefore, statement I alone is not sufficient to answer the question. Statement II alone tells us that Jyoti, who is the daughter-in-law of Kamal, has a son and a daughter. However, we don't know if Meghna is Jyoti's daughter or not. Therefore, statement II alone is not sufficient to answer the question. Both statements I and II together provide the necessary information to determine the number of brothers Meghna has.

Among P, Q, R, Sand T, sitting in a straight line, facing North, who sits exactly in the middle of the line?
I. S sits third to the left of Q. S is an immediate neighbour of both P and T.
II. Two people sit between T and R. R does not sit at either of the extreme ends. P sits second to the right of T.
Correct Answer
B. If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
Explanation
Statement II alone is sufficient to answer the question. According to statement II, two people sit between T and R and R does not sit at either of the extreme ends. Since the people are sitting in a straight line, facing North, and R cannot sit at either of the extreme ends, it means that T must be sitting at one of the extreme ends. Therefore, the person who sits exactly in the middle of the line must be S. Statement I is not necessary to determine the answer.
