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 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 | ||
| Jai Chand (JC) | Event 1: JC comes in | |
| Event 2: Sohan Singh (SS) comes in. | ||
| Event 3: Shail Munshi (SM) comes in. | ||
