Simple stack concept.We have to find the possible combination of popping a stack order can be-
1)push 1, pop 1, push 2, pop 2,push 3, pop 3,push 4, pop 4,push 5, pop 5 so,letter popping order 1,2,3,4,5 so option d correct.
2)push 1,push 2,push 3, pop 3,pop 2,push 4,pop 4,pop 1,push 5,pop 5 so,popping order 3,2,4,1,5.so option c correct.
3)push 1,push 2,pop 2,push 3,push 4,pop 4,pop 3,push 5,pop 5,pop 5 so,popping order 2,4,3,5,1 so,option a is correct.
4)push 1,push 2,push 3,push 4,pop 4,push 5,pop 5.Now not possible to pop 2 without popping 3.so this cannot be a popping order.so,option b is not correct.

b;
use stack concept;
12 years agoHelpfull: Yes(19) No(5)
option a is also possible because.....
boss puts in first turn..1 and 2 and she types top one i.e 2
then boss puts 3 and 4... she types top one i.e 4 and then 3

while she is typing 3 boss puts 5 on top....
so next she types 5
dn lastly 1

hence, possible combination cn be
24351 also.... this may b a dummy ques... correct me if iam wrong

b) Not possible coz if 4 and 5 has been removed from the top, then there should be 3 after it. (Not the 2)
12 years agoHelpfull: Yes(5) No(3)
d)12345 because it is clear that there is chance of taking in other i mean a,b,c orders but there is no chance of taking 12345

after getting the type of no 1 text,,boss will not provide the same text to type again...at option b thre is no 1 is 2nd tym provided by boss,,so ans is B
10 years agoHelpfull: Yes(1) No(1)
Answer a is correct

b is the correct one, because if 4th is removed first,it means it,s on top of stack,then 5,then 3 should come not 2,as it,s in order.

only option B is correct
9 years agoHelpfull: Yes(0) No(0)
Option a) cannot be the answer.
Because, when 2 letters are kept on top, the secretary takes the 2nd letter first.
Then, the 3rd letter is placed by the boss on top.
Then the fourth letter is placed.
Then, he can take the 4th letter now.
Now, he takes the 3rd letter.
Then the boss places the 5th letter.
Secretary now takes the 5th letter.
Then finally he can take the 1st letter from the pile to type.

b is write answer
9 years agoHelpfull: Yes(0) No(0)
Ans: (b)
Assuming the typist types letter No 4, the boss comes and place letter No 5 on top. There are only five letters and so, beneath the letter No 5 should be letter No 3. Hence the sequence under option (b) is not correct.
