SET-1
There are five people. One of them shot and killed one of the other five. Which man is the murderer?
1. Dan ran in the NY City marathon yesterday with one of the innocent men.
2. Mike considered being a farmer before he moved to the city.
3. Jeff is a topnotch computer consultant and wants to install Ben's new computer next week.
4. The murderer had his leg amputated last month.
5. Ben met Jack for the first time six months ago.
6. Jack has been in seclusion since the crime.
7. Dan used to drink heavily.
8. Ben and Jeff built their last computers together.
9. The murderer is Jack's brother. They grew up together in Seattle.

Ans. Jeff is the Killer
Approach:- 5 persons- Dan,Mike,Jeff,Ben,Jack
Now Dan can't be murderer since he ran marathon and given murderer had his leg amputated
Murderer is Jack's Brother so persons left Mike,Jeff,Ben
Given Mike being farmer before he moved to the city but Jack's brother aka murderer grew up in seattle So Mike is also not Murderer
This gives Jeff and Ben getting a clue from 5th Ben met jack first time 6 months ago
So clearly jeff and Jack are brothers and Jeff Killer :D

OA
Answer
1. Jack is not the murderer, because he is the brother of the murderer. 2. Dan can't be the murderer since he ran a marathon, and the murderer recently had his leg amputated, and wouldn't be running a marathon of any magnitude that quickly. 3. Ben is not the murderer if he just met Jack, since Jack and the murderer grew up together. 4. This leaves Jeff and Mike. Since Jeff is still alive (he wants to install a new computer next week, present tense) he must be the murderer. Mike also didn't grow up with Jack. It has been determined that Jack, Dan and Jeff are all alive. Ben must also be alive since Jeff plans to install Ben's computer next week. This means that Jeff killed Mike.

hey, try to make venn diagram for the given soln, it will be easily understoodhere,
exactly(3)/exactly(1)=1/6
exactly(2)/exactly(1)=1/4
exactly(3)/exactly(0)=4/1
Also, n(I)=140, n(A)=170, n(C)=170
Now, I+A+C= Exactly(1)+ 2.Exactly(2)+ 3.Exactly(3)
put all values in rhs in terms of Exactly(1) using above equations and u will get Exactly(1)=240, Exactly(2)=60, Exactly(3)=40, Exactly(0)=10
now,
1. as only C is 80
this means only I + only A = Exactly(1)- only C i.e. 160
now, n(C)= only C+ Exactly(3) + rest2(which are among the set of exactly 2)
this means 2 of the three exactly(2) = 50= r
now, n(A)+n(I)= only A+ only I + r+ exactly(3) + ans(what u want)
therefore ans is 10
2. ex(2)= 30+ rest
this means rest exactly(2)= 30 = t , which is in I
now I= t+ only I + Exactly(3)
this means only I= 70
exactly(3)/exactly(1)=1/6
exactly(2)/exactly(1)=1/4
exactly(3)/exactly(0)=4/1
Also, n(I)=140, n(A)=170, n(C)=170
Now, I+A+C= Exactly(1)+ 2.Exactly(2)+ 3.Exactly(3)

SET 4
Five people A, B, C, D and E stay in five different rooms of GMVN Hotel. Their rooms lie in a row and are numbered serially from '101' to '105'. The number of C's room is smaller than that of E's room which in turn is smaller than that of A's room. Moreover, the difference between the room numbers of E and C is the same as the difference between the room numbers of A and E. D is in room number 104 and his room is not next to E's room. What is E's room number?
