Directions (6-10): In each of the questions below are given three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read both the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Give answer—
(1) if only conclusion I is true.
(2) if only conclusion II is true.
(3) if either conclusion I or conclusion II is true.
(4) if neither conclusion I nor conclusion II is true
(5) if both conclusions I and II are true.

ANSWERS
1. (1)
Except (1) all are multiples of 11.

2. (5)
First three letters are changed to next letter in alphabetic order and written in reverse order. Similarly last three letters are changed to next letter and then written in reverse order. The middle letter is changed to previous letter.
Hence the code should be SUTDTNB.

3. (1)
The first letter moves to second position, second letter moves to fourth position, third remains at its position and last letter moves to first position.

4. (1)
Y’s position from the right end = 5 + 11 = 16
Y’s position from the left end = 40 + 1 – 16 = 25th

5. (5)
The tallest person will be either R or Q.

6. (1)


7. (3)

8. (4)
