Every day a widget supplier supplies widgets from the warehouse ( W ) to four locations - Ahmednagar (A), Bikrampore (B), Chitrachak (C), and Deccan Park (D). The daily demand for widgets in each location is uncertain and independent of each other. Demands and corresponding probability values (in parenthesis) are given against each location (A, B, C, and D) in the figure below. For example, there is a $40 \%$ chance that the demand in Ahmednagar will be $50$ units and a 60\% chance that the demand will be $70$ units. The lines in the figure connecting the locations and warehouse represent two-way roads connecting those places with the distances (in km ) shown beside the line. The distances in both the directions along a road are equal. For example, the road from Ahmednagar to Bikrampore and the road from Bikrampore to Ahmednagar are both $6 \mathrm{~km}$ long. <img src="https://balti.aftergrad.in/questions/dFeskO7wOUTtk6T" width="500px"/> Every day the supplier gets the information about the demand values of the four locations and creates the travel route that starts from the warehouse and ends at a location after visiting all the locations exactly once. While making the route plan, the supplier goes to the locations in decreasing order of demand. If there is a tie for the choice of the next location, the supplier will go to the location closest to the current location. Also, while creating the route, the supplier can either follow the direct path (if available) from one location to another or can take the path via the warehouse. If both paths are available (direct and via warehouse), the supplier will choose the path with minimum distance.

If the last location visited is Ahmednagar, then what is the total distance covered in the route (in km)?

<img src="https://balti.aftergrad.in/questions/21LLXDhyupZcj3b" width="400px"/> Given above is the schematic map of the metro lines in a city with rectangles denoting terminal stations (e.g. A), diamonds denoting junction stations (e.g. R) and small filled-up circles denoting other stations. Each train runs either in east-west or north-south direction, but not both. All trains stop for 2 minutes at each of the junction stations on the way and for 1 minute at each of the other stations. It takes 2 minutes to reach the next station for trains going in east-west direction and 3 minutes to reach the next station for trains going in north- south direction. From each terminal station, the first train starts at 6 am; the last trains leave the terminal stations at midnight. Otherwise, during the service hours, there are metro service every 15 minutes in the north-south lines and every 10 minutes in the east-west lines. A train must rest for at least 15 minutes after completing a trip at the terminal station, before it can undertake the next trip in the reverse direction. (All questions are related to this metro service only. Assume that if someone reaches a station exactly at the time a train is supposed to leave, she can catch that train).

A person standing at an intersection can see along straight lines to other intersections that are in her line of sight and all other people standing at these intersections. For example, a person standing at intersection g can see all people standing at intersections b, c, e, f, h, and k. In particular, the person standing at intersection g can see the person standing at intersection e irrespective of whether there is a person standing at intersection f. $$\newline$$ <img src="https://balti.aftergrad.in/questions/A2Q5gv0fTc5O3AA" width="300px"/> $$\newline$$ Six people U, V, W, X, Y, and Z, are standing at different intersections. No two people are standing at the same intersection. $$\newline$$ The following additional facts are known. $$\newline$$ <ol> $\newline$ <li>X, U, and Z are standing at the three corners of a triangle formed by three street segments.</li> $$\newline$$ <li>X can see only U and Z.</li> $$\newline$$ <li>Y can see only U and W.</li> $$\newline$$ <li>U sees V standing in the next intersection behind Z.</li> $$\newline$$ <li>W cannot see V or Z.</li> $$\newline$$ <li>No one among the six is standing at intersection d.</li> $\newline$ </ol>
