In such type of questions, a few essential criteria for selection of a group of items are given. The candidate has to keep these conditions in mind and make the required selection as per the directions given in each question.
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 :
(i). If program P is to be operated on a day, V cannot be operated on that day.
(ii). If Q is to be operated on a day, T must be one of the programs to be operated after Q.
(iii). If R is to be operated on a day, V must be one of the programs to be operated after R.
(iv). The last program to be operated on any day must be either S or U.
If R is operated at third place in a sequence, which of the following cannot be the second program in that sequence ?
If R is operated at third place, it will be followed by V at the fourth place and S or U at the end.
So, Q which must have T as one of the programs after it, cannot be at the second place.
