Logical Reasoning – Set – Seven candidates, Akil, Balaram

The following set contains four questions related to Data Interpretation. Choose the best answer to each question.

Seven candidates, Akil, Balaram, Chitra, Divya, Erina, Fatima, and Ganeshan, were invited to interview for a position. Candidates were required to reach the venue before 8 am. Immediately upon arrival, they were sent to one of three interview rooms: 101, 102, and 103. The following venue log shows the arrival times for these candidates. Some of the names have not been recorded in the log and have been marked as ‘?’.

Additionally here are some statements from the candidates:

Balaram: I was the third person to enter Room 101.
Chitra: I was the last person to enter the room I was allotted to.
Erina: I was the only person in the room I was allotted to.
Fatima: Three people including Akil were already in the room that I was allotted to when I entered it.
Ganeshan: I was one among the two candidates allotted to Room 102

Q 1. What best can be said about the room to which Divya was allotted?
a) Definitely Room 102
b) Definitely Room 101
c) Either Room 101 or Room 102
d) Definitely Room 103

Q 2. Who else was in Room 102 when Ganeshan entered?
a) No one
b) Chitra
c) Akil
d) Divya

Q 3. When did Erina reach the venue?
a) 7:10 am
b) 7:15 am
c) 7:45 am
d) 7:25 am

Q 4. If Ganeshan entered the venue before Divya, when did Balaram enter the venue?
a) 7:15 am
b) 7:25 am
c) 7:45 am
d) 7:10 am

Solution:
From Chitra’s statement it is clear that Chitra and Fatima can not be in the same room. And also there will be 4 people in Fatima’s room and at least two people in Chitra’s room.
As there are only 7 people and 3 rooms . So the only possible case is that there must be exactly 1, 2 and 4 people in each room in any order.
Now from Balram’s statement it is clear that there were more than 2 people in room number 101. So number of people in room 101 = 4
As Ganeshan was in room number 102 so he/she must be there with Chitra as chitra was last one to enter his room. And E would be the last one to come.
These information can be tabulated as bellow:

Time (am)	7:10	7:15	7:25	7:30	7:40	7:45
Candidate	Akil, G/D	G/D/B	B/G	Chitra	Fatima	Erina

 And

Room no.	101	102	103
Candidate	Akil, , Divya (D) Balram (B), Fatima	Ganeshan , Chitra	Erina

 Now all questions can be answered
1. b) Definitely Room 101
2. a) no one
3. c) 7 : 45 am
4. b) 7 :25 am
