✅ Correct Option: 1
Slide 1/9

Understanding the set :-

  1. Seven candidates (Akil, Balaram, Chitra, Divya, Erina, Fatima, and Ganeshan) arrive for interviews. Upon arrival (before 8:00 AM), they are assigned to one of three rooms: 101, 102, and 103.
  1. You’re given:

a) A log of arrival times (with some names missing, marked as "?").

b) Statements from 5 candidates providing clues about their room placements and order of entry.

  1. Understanding the Table:

a) The image shows a time log where:

b) The left column shows timestamps (from 7:00 AM to 7:45 AM).

c) The top row shows the three interview rooms: 101, 102, 103.

d) Cells contain names or “?” to indicate who entered which room at that time.

This means: each row represents a minute-wise arrival, and each cell indicates who entered which room at that time.

Now, let's solve the set using other clues and constraints.

Room no.CandidatesName
101
1022Ganesham
103

Clue 5 says,

Ganeshan was one among the two candidates allotted to Room 102.

=> there were two candidates who were allotted room 102, and Ganeshan was one among them.

Room no.CandidatesName
1014
1022Ganesham
1031

Now, according to clue 3,

Erina was the only person in the room I was allotted to.

=> There is one of the room who has only 1 candidate.

=> The other room will have 7−2−1=47 - 2 - 1 = 4 candidates.

But, clue 1 says,

Balaram was the third person to enter Room 101.

=> Room 1 will have 4 candidates and room 3 will have 1 candidate.

Room no.CandidatesName
1014,, Balaram, _
1022Ganesham
1031

Clue 1 says,

Balaram was the third person to enter Room 101.

we can directly add this to the table.

Room no.CandidatesName
1014__, __, Balaram, __
1022Ganesham
1031Erina

According to clue 3,

Erina was the only person in the room she was allotted .

=> Erina was in room no. 103, as it only have 1 candidate in the room which will be Erina.

This also we can directly add to the table.

Room no.CandidatesName
1014__, __, Balaram, Fatima
1022Ganesham
1031Erina

Clue 4 says,

Fatima said three people including Akil were already in the room that she was allotted to when she entered it.

=> Fatima was in room 1 and also the 4th and the last person to enter the room

Room no.CandidatesName
1014__, __, Balaram, Fatima
1022Ganesham, Chirta
1031Erina

According to clue 2,

Chitra was the last person to enter the room she was allotted to.

Now, as we can see, in room 101, Fatima was the last person to enter, and Erina was the only candidate in room 103.

=> Chitra will be in room 102 and will be the last person to enter in the room.

Room no.CandidatesName
1014Akil, Diyva, Balaram, Fatima
1022Ganesham, Chirta
1031Erina

Now, from the table given in the question, we can see,

Akhil is the first person to enter the venue.

=> In room 101 Akhil will be the first person to enter

Therefore, Divya will be the second person to enter room 101.

Room no.CandidatesName
1014Akil, Diyva, Balaram, Fatima
1022Ganesham, Chirta
1031Erina

From the table we can see that,

Fatima at 7: 40 and Chitra at 7:30 were the last person to enter their respective room number 101 and 102. So Erina entered at

7:45.
