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 the program sets R and W are to be operated on the first day, which of the following could be the other programs on that day ?**

** Option:**

**A.**P, T, V

**B.**Q, S, V

**C.**Q, T, V

**D.**T, S, V

**E.**T, S, V

**Answer: E . T, S, V**

** Justification:**

Since R is operated, so V must also be operated.

Also, S or U is to be taken at the end.

So, the possible combinations are Q, S, V and T, S, V.

Now, Q must have T as one of the programs after it, which is not possible. So, Q, S, V is incorrect.
