Question 3 - 2
Question 4 - 4
APPROACH :
1) 1 st you answer Q3 since that is essentially what you have to figure out in the first place.. Your thinking for the entire section starts from that very question.. so ans to Q3 is option 2
2) now Q1...to ans this Q you have to first ans rest of the Q.. so you ans this Q last.. so ans to Q1 is option1
3) then you answer Q2 ..
i) it's not 0 since that would lead to ans to Q4 as option3.. proving your ans to Q2 wrong
ii) it's not 2 since non of the prev answered Q has 3 as option.. so this to be true you need ans to Q2 and Q4 as option 3.. but you chose option 1 for Q2!!.. so option 1 is not the ans..!!
iii) it is not option 4 because that does not give an answer to Q4
iv) so it is option 3!
4)ans to Q2 gives ans to this Q as option4
umm.. there has been a mistake in this solution..
DeleteAnswer is
Delete1. 1
2. 4
3. 2
4. 1
The reason is that-
- First of all we need to answer Q3. to start the thinking process
- Then going to Q1. we can say that its answer is 1 or 2
- Then to Q2. its answer can't be 0 as then answer of Q4. will be 3. Also it can't be 2 as Q3 and Q1 dont have 3 as an answer. Now for answering we will have to tell the questions which are having option 3 as an answer which have been answered before thus if we answer it as 1 then Q2. will also have option 3 as an answer and the answer will become option 1 which is again not possible. Thus as a conclusion we can say that the answer of Q2. is NONE OF THESE.
- The answer of Q4. is obviously 1 now.
- To answer Q1. we need to answer all other questions. Thus ans of Q1. is 1
Corrected solution :
ReplyDeleteQ1 - 1
Q2 - 3
Q2 - 2
Q4 - 2
APPROACH:
1) 1st you ans Q3.. since that is from where your thinking for this section starts.. so ans to Q3 is option(opt) 2
2) ans to Q1.. ambiguity for ans to this Q is between opt 1 & 2.. let this be opt 1..(justified later)
3) now Q2 ..
i) it is not 0 since that would give ans to Q4 as opt 3.. proving your ans to Q2 wrong
ii) it is not 2 since your ans to Q1 or Q3 were not opt 3 so for this ans to be right you need ans to Q2 and Q4 as opt 3.. but you chose ans to Q2 as opt 1!!.. so opt 1 is not the ans!!
iii) it is definitely not opt 4
iv) so ans to Q2 is opt 3
4) ans to Q2 gives ans to Q4 as option 2
Justification for Q1 ans >> it is not opt 2 because opt 2 has already been an ans to Q3 and Q4 ..

Please read the solution and understand it
Solution-
We cant anawer Q1 & Q2 first as we cant predict the last question
or the no. of options with 3 as correct option and Q4 is after Q2 so we answer Q3 first ehose obvious answer will be 2) 3
Now as Q4 is after Q2 so next cant be this.
neither can we say anything about Q2 so the only possible answer to Question1 is 2)4 as 3)2 & 4)3 is clearly not possible as we have anawered Q3 and Q4 is present after Q2 also we are answering Q1 now. so finally we are left with 2)4
Now we can only answer Q2 before Q4
Answer to this cant be 4) none of these
neither it can be 1)2 as after this we will be with only one Question. it cant be 2)0 as question 4 doesnt contain any answer as 0 so only 3)1 is possible
now ultimately Q4 says ANSWER ( not the option) to question 2 which is 1 so the final answer is 4)1
Note in the last part question has asked the answer not the option no. so the answer is 1 not 3 which is the option no.
Please read this carefully .
well it does say ANSWER and not option.. but Q3 has ans 0,1,2 & none of these..
Deleteso shouldn't Q4 have same ans in different order??? which is not so!!
That says.. they meant OPTION and not ANSWER
Its not necessary for Q 4 to contain 0,1,2,and none of these in different order as one would have to check this option only due to which 0 & none couldnt be the answer. so we will then think of answer 1 & 2 . But if u r right then paper setters should write the word option not answer due to which many would have done wrong.
DeleteAnswer is
ReplyDelete1. 1
2. 4

4. 1
The reason is that-
- First of all we need to answer Q3. to start the thinking process
- Then going to Q1. we can say that its answer is 1 or 2
- Then to Q2. its answer can't be 0 as then answer of Q4. will be 3. Also it can't be 2 as Q3 and Q1 dont have 3 as an answer. Now for answering we will have to tell the questions which are having option 3 as an answer which have been answered before thus if we answer it as 1 then Q2. will also have option 3 as an answer and the answer will become option 1 which is again not possible. Thus as a conclusion we can say that the answer of Q2. is NONE OF THESE.
- The answer of Q4. is obviously 1 now.
- To answer Q1. we need to answer all other questions. Thus ans of Q1. is 1
if we answer NONE OF THESE in Q2 that would mean the no of answers as 3 is not 0, 1 or 2 and that would thus mean that no f correct options as 3 is 3 or greater than 3 which is not possible so your Q2's answer is wrong which in turn makes Q4 wrong.
DeleteActually here None Of these means that we cant answer this question with the given information. Understand. I have even explained it above
Deleteif no of these means that information is not enough then i think technothlon guys would hav give "data not sufficient" as an option. THE GUYS WHO MAKE THESE PAPERS ARE NOT FOOLS.
DeleteThey might have given none of these as an option to challenge the students
DeleteQ1- 1
ReplyDeleteQ2- 3
Q3- 2
Q4- 2
Approach:
1. we cant answer the 1st question without answering the other three because we need to tell the last question we would do..so practically Q1 is the last question therefore its answer is (1.)
2. The basic question that we need to answer first is Q3 itself as Q1 needs to be done at last, Q2 cant be done at first because it is asking for no of 3's as correct solution, Q 4 need to be done after Q2 so that leaves only Q3 to be done at first.
3.Now for answering Q2 we can easily cut 1st option and the last option as they are not possible because that we hav already answerd 2 Q's. so wat we need to do is mark option 3 as it says only one 3 appears as solution which appears in that question itself.
4. now Q4 has a direct answer
we followed all the rules and condition and got the correct answer (atleast i think that it is correct).
How can you cut the last option??
Deleteif we answer NONE OF THESE in Q2 that would mean the no of answers as 3 is not 0, 1 or 2 and that would thus mean that no f correct options as 3 is 3 or greater than 3 which is not possible so your Q2's answer is wrong which in turn makes Q4 wrong.
Deletesorry posted the above comment on wrong post. your answer is correct
DeleteRead the reply in previous comment
Deletethats a beautiful answer
Deletekeep it up
Thanks. Now you understood why the answer of Q2. should be 4. Is it correct??
DeleteThanks
DeleteI cut the none of these as correct ioption since if we choose no of these than we are presuming that answer is not 0, 1 or 2 and thus it also mean question with 3 as correct option are greater than 2.
DeleteActually here None Of these means that we cant answer this question with the given information. Understand. I have even explained it above
DeleteNone of these mrans not anyone from the answer that does not means that we cant answer the question but it means that its might have another options else 0 , 1 , 2

ReplyDeleteQuestion 1- option 1
ReplyDeleteQuestion 2- option 3
Question 3- option 2
Question 4- option 4
Question 1- (1)
ReplyDeleteQuestion 2- (3)
Question 3- (2)
Question 4- (4)
Question 1 - (1) .If we could answer this question before the last one, then we knew the last question that will be answered. So the last question to be answered is Question 1.
ReplyDeleteQuestion 2 - (3) .As all the 4 questions have different options as their respective answers, hence there is only question that has option (3) as correct.
Question 3 - (4) .The fourth question is the basic question to be answered first.
Question 4 - (2) .The answer to question 2 is option 3. So the answer to this question is '3' which is option (2).
Q.1 option(1) as per the rules Q.4 is to attempted after Q.2 and so the last ques. will be (3)
ReplyDeleteQ.2 option(3)because it is the only ques. which has a ans. as option (3)
Q.3 option(2)
Q.4 option (2)
