At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?

The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day? Correct Answer T, S, V
Given:
1. If program P is to be operated on a day, V can’t be operated on that day.
2. If Q is to be operated on a day, T must be one of the programs to be operated after Q.
3. If R is to be operated on a day, V must be one of the programs to be operated after R.
4. The last program to be operated on any day must be either S or U.
Conditions that follows:
3. If R is to be operated on a day, V must be one of the programs to be operated after R.
| Options | Possible Combination | Reasons |
| 1. | P, T, V | Not possible, according to condition 1, P and V can't be operated on that day. |
| 2. | Q, S, V | Not possible, according to condition 2, T must be operated one of the days after Q and T is not in the combination. |
| 3. | Q, T, V | Not possible, according to condition 4, the last program to be operated on any day must be either S or U. |
| 4. | T, S, V | Possible, It follows conditions 3 and 4 and does not violate any given condition. |
Hence, T, S, V is the correct answer.
