Question

Which movie was screened on Friday?

• A. Chak De
• B. Sholay
• C. Anand
• D. 3 Idiots

Hint:

For consecutive-pair constraints, first list all legal slots for each pair, then use “spacing” clues (like one between X and Y) and day bans (e.g., not Mon/Fri) to lock positions.

Answer 1

The Correct Option is C

Step 1: Encode the “immediately after” constraints.
S is immediately after DBJ - \fbox{DBJ, S} must occupy two consecutive days.
C is immediately followed by A - \fbox{C, A} must also be consecutive.
DBJ and C cannot be on Monday or Friday.
Step 2: Place \fbox{DBJ, S.}
Possible slots for \fbox{DBJ, S}: (Mon,Tue), (Tue,Wed), (Wed,Thu). But DBJ cannot be Monday, so \fbox{DBJ, S} can be either \fbox{Tue, Wed} or \fbox{Wed, Thu}.
Step 3: Use the “one movie between S and 3I.”
If S is on Wed (from \fbox{Tue,Wed}), then 3I must be on Mon or Fri. - Fri is impossible because then C (not allowed on Fri) would need to be Thu to place \fbox{C, A} as (Thu,Fri). So take 3I on Mon. This satisfies “one between S and 3I” (Tue sits between Mon and Wed).
Step 4: Place \fbox{C, A.}
Remaining days: Thu and Fri. Since C cannot be Fri, we must have \fbox{C, A} = (Thu, Fri).
Thus the full schedule becomes: Mon 3I, Tue DBJ, Wed S, Thu C, Fri \boxed{A}. Hence Friday’s movie is \boxed{\text{Anand}}.
