Denote the first step by step 1 and second step by step 2 etc.

Q1. If Mr. A is on the first step, Which of the following is true?
(a) Mr. B is on the second step
(b) Mr. C is on the fourth step.
(c) A person Mr. E, could be on the third step
(d) Mr. D is on higher step than Mr. C.


Q2. If Mr. E was on the third step & Mr. B was on a higher step than Mr. E which step must be vacant
(a) step 1
(b) step 2
(c) step 4
(d) step 5
(e) step 6

Q3. If Mr. B was on step 1, which step could A be on?
(a) 2&5 only
(b) 3&5 only
(c) 3&4 only
(d) 4&5 only
(e) 2&4 only

Q4. If there were two steps between the step that A was standing and the step that B was standing on, and A was on a higher step than D , A must be on step

(a) 2
(b) 3
(c) 4
(d) 5
(e) 6

Q5. Which of the following is false

(3i Infotech Question)
arun kumar   1). If A is on first step. Then C is on 3th step. B and D come together. So, B and D are higher step than A and C.
hence (D) is the answer.

2). If E is on third step and B is on higher step. Then, C,_A should not come below or above E. 
Thus E should come in between C and A. Then vacant step is first.
Hence (A) is the answer.

3). If B is on step 1, then D is on step 2. 
If C is on step 5 then A is on 3
If C is on step 6 then A is on 4
hence (C) is the answer.

4). From the possible combination. A is on step 4.
Hence (C) is the answer.

5). i). B and D are next to each other so one is at odd and one is at even. 
so, i is wrong.
ii). A and C are next to each other. Thus both have the same numbered steps (i.e odd or even). so ii is true
iii). A and E can be on a step next to vacant is false.
So, (C) is the answer.
