Hi Sir,

Regarding the question no:3 about the "who is safe" question, i need a clarification for the answer you are provided.

It's mentioned in the solution pdf document that "We do not need to check for others as the bullet will not cross x = 82."

Can you please explain how we are deriving this conclusion? (Its not mentioned in the question too)

According to my understanding in the real world scenario, if a bullet from a sniper hit on a person (in our case "N")  ,the bullet will pass again on the same direction and hit the ground at 90m, where in our case "M" is standing. So the bullet will hit the foot of the person "M". 

Since we are discussing about the straight line scenarios, i didn't consider the deviation of the bullet after hitting the first person and its mentioned in the question that the range of the gun is too short and consider the path bullet is straight line. Moreover it's not mentioned anywhere in the question that, once the bullet hit a person the bullet will not move further.

My answer for this question was "Only K and N are safe."

So i feel this answer is the correct one since we are discussing about "sniper. Looking for a revert for this please.

According to your revert i can change my perception of the upcoming questions. 

Note: According to my understand the word "SAFE" in our scenario is not only a death case , a person who got injured during the Gun shot in his "foot" too is not a safe position.Please correct me if am wrong.

Rgds,

Prasanth

Absolutely!! As per my understanding, bullet from a real world sniper can penetrate 3 people before it would loose enough velocity and sway away from a straight line too much to be effective. I answered considering the subjectivity of the question, as it was not mentioned anywhere in the question about number of targets bullet would hit. If it was not a sniper bullet but a normal bullet than I would have agreed with the fact that bullet would stop after hitting target M.

Regards,
Ayush

Hi All,

I had gone though some questions asking for the same query in this forum.

let us all go through the given answers for the question. The below are the options.


1. All workers are safe.
2. All the workers are safe except K.
3. Only K and N are safe.
4. No one is safe.
5. Only K is safe.
6. All the workers are safe except M.

If we need to consider the bullet will stop after hitting a person either it need to mention in the question as a condition or the given optional answers should not give any confusion regarding this perception. The given optional answer no: 3,4 and 5 are directly hitting our common-sense that, the bullet will pass through the body after hitting a person. Either it need give the clarification in the question or it should not give the optional MCQ's which is directly clarifying this query.

Moreover somebody was mentioning in the forum that, there a was query regarding this question before submission, and it got answered by the team that " Bullet will not disturb any other person once it hit a person". Please note that, thousands of queries flying in this forum in a daily basis. either it need to mention in the question or a official mail from the concerned person is required these type of corrections.


rgds,

Prasanth.

Yes ,I also agree. After calculating ranges for all the workers and Based on the fact that L and M lie within the unsafe range where bullet miight hit, I had also selected "Only K and N are safe " as answer.
