This question looks extremely complicated due to the multiple statements, but the main issue required to be resolved while solving this question is the structure of the diagram. While solving this question concentrate mainly on who is present in the bar at different times of the day and correlate this information to the statements. Also try to number the events so as to give order to the various going-ins and coming-outs of the people. The following reaction tracker table gives the step by step reactions to the clues in the question.
| Statement of | Reaction | |
| Jai Chand (JC) | Event 1:JC comes in | |
| Event 2: Sohan Singh (SS) comes in. | ||
| Event 3: Shail Munshi (SM) comes in. | ||
| Constraint:JC leaves with Deepak Garg (DG) leaving Jai Prakash (JP) and Vinod Rai (VR) in the bar. | ||
| Jai Prakash (JP) | Event (Number not known):JP and VR enter. | |
| Constraint:JC and someone else was there. | ||
| Shail Munshi (SM) | Event: SM enters | |
| Constraint: Meets JC, SS and DG | ||
| Sohan Singh (SS) | Event x: SM leaves | |
| Event (x + 1): SS leaves | ||
| Deepak Garg (DG) | Event: DG enters. | |
| Constraints: Meets SS, SM, JP and VR during his first visit. | ||
| Event: DG and JC leave. | ||
| Constraint:JP and VR are there when DG enters again. (No one else present) | ||
| Pradeep Kumar (PK) | Event: PK enters | |
| Constraint: Only JP and DG are present at this time. | ||
| Vinod Rai (VR) | No info. | |
| Deductions: When JP and VR enter only 2 people are there. We also know the first 3 events—JC enters, SS enters and SM enters. Also, DG meets SC, SS, SM, JR & VR in his first visit. | ||
| This gives us that: Event 4: DG enters Event 5: SM leaves Event 6: SS leaves Event 7:JP and VR enter (at this time only JC and DG are there) Event 8:JC and DG leave (Now only JP and VR are present) Event 9: DG comes back again (now JP, VR and DG are inside) Event 10: VR leaves (Since when PK enters only JP and DG are there) Event 11: PK enters Event 12: PK leaves |
