A BPO has assigned duty to nine operators - Abdulla, Ballal, Chandan, Dogra, Eshita, Falguni, Ganguli, Henri and Indra - on Monday, January 05, 2009 from 00:00 hours. Each operator commences duty at any of the following hours: 00:00 hrs, 04:00 hrs, 08:00 hrs, 12:00 hrs, 16:00 hrs and 20:00 hrs. At any point in time, at least one operator is required, to take clients' calls. Each operator works continuously for eight hours. All operators located at any single location start work simultaneously. The operators took training in five different colleges -Abhiman College, Sutanama College, Gutakal College, Barala College and Khatanama College. These colleges are located in the cities Jamshedpur, Pune, Noida, Hyderabad and Mangalore, not necessarily in that order. The operators operate from the cities where their respective colleges are located.
Indra operates alone from a city other than Mangalore and Jamshedpur. Operator(s) trained in Abhiman College will start working at 12:00 hrs. Only Dogra and Falguni operate from Pune, but they are not trained in Gutakal College. Three of the operators took training from Sutanama College, and they operate from Noida. The operator(s) from Jamshedpur will start working at 0:00 hrs. Abdulla and Henri operate together as a two member team from a single location. They do not operate from Mangalore. No operator(s) will join at 20:00 hrs. Ballal, who alone operates from his location, was not trained in Barala College, and will commence his duty four hours after the operator(s) trained in Gutakal College. The operator(s) trained in Barala College operate from Hyderabad. The number of operator(s) trained in Khatanama College is same as the number of operator(s) trained in Barala College.
Let A, B, C, D, E, F, G, H and I represent Abdulla, Ballal, Chandan, Dogra, Eshita, Falguni, Ganguli, Henri and Indra.
Indira operates alone from Pune, Noida or Hyderabad and only Dogra and Falguni operate from Pune, while there are three operators from Noida
who have studies in Sutanama College. Since Indira works alone, she cannot be from Pune or Noida.
Thus, Indira works alone from Hyderabad.
Thus, D, F- Pune - 2
I- Hyderabad - 1
-Noida- 3
We are given, Abdulla and Henri operate together as a two member team from a single location and they do not operate from Mangalore.
Thus, A and H work from Jamshedpur and Only 1 person work from Mangalore.
D, F- Pune - 2
I- Hyderabad - 1
- Noida- 3
A, H- Jamshedpur
- Mangalore- 1
Ballal operates alone from his location.
Thus, we get:-
D, F- Pune - 2
I- Hyderabad - 1
C, E, G - Noida- 3
A, H- Jamshedpur
B - Mangalore- 1
Three of the operators took training from Sutanama College, and they operate from Noida
Thus, C, E and G took training from Sutanama College.
The operator(s) trained in Barala College operate from Hyderabad.
Thus, I is trained in Barala College.
The number of operator(s) trained in Khatanama College is same as the number of operator(s) trained in Barala College.
Thus, only 1 person is trained from Khatanama College and that person is B.
Only Dogra and Falguni operate from Pune, but they are not trained in Gutakal College.
Thus, D and F are trained in Abhiman college.
Thus, A and H are trained in Gutakal College.
The operator(s) from Jamshedpur will start working at 0:00 hrs
Hence, A and H will start working from 0.
Operator(s) trained in Abhiman College will start working at 12:00 hrs.
Hence, D and F will start working from 12
Ballal will commence his duty four hours after the operator(s) trained in Gutakal College
Hence, B will commence his duty from 4.
Thus, the final table is:-
From the table, if Chandan, Eshita and Ganguli start working at 4:00, then between 4:00 to 8:00, there will be 6 people working. Thus, option B is incorrect.
Hence, option B is the correct answer.
