Directions: Read the table carefully and answer the following question. The table shows the data about distance (km) covered from one point to another point by the vehicle used between each point and speed of each vehicle (km/h). Note: (i) If one person wants to travel from P to S, then he/she can only use a vehicle available at the point P. (ii) ** means there is no direct connection between given points. | | P | Q | R | S | Transport Vehicle | Speed (km/h) | |---|---|---|---|---|---|---| | P | 0 | 360 | ** | 780 | Train | 60 | | Q | 540 | 0 | ** | 600 | Taxi | 50 | | R | 420 | 720 | 0 | ** | Bus | 40 | | S | 630 | ** | 900 | 0 | Bike | 45 | If Vasu travels from P to S and Sanjeet travels from Q to P, then find the difference between the maximum distance travelled by both of them.

### Concept & Table Interpretation The problem requires extracting the direct travel distances from the given data table for specific origin-destination pairs. $$ \text{Difference} = \text{Distance}(P \to S) - \text{Distance}(Q \to P) $$ ### Step-by-Step Solution 1. Identify Vasu's travel route: Vasu travels from point P to point S. 2. According to the table, reading the row for origin P and column for destination S, the direct distance is 780 km. 3. Identify Sanjeet's travel route: Sanjeet travels from point Q to point P. 4. According to the table, reading the row for origin Q and column for destination P, the direct distance is 540 km. 5. Calculate the difference between these two primary direct distances: $780 - 540 = 240$. ### Exam Strategy & Shortcut When questions use confusing terminology like "maximum distance" but provide options that strictly match the difference between direct table lookups, prioritize the direct values. Always double-check row vs. column mapping (Origin is row, Destination is column). ### Common Pitfall A common mistake is assuming the distance from P to Q is the same as Q to P. In this specific table, $P \to Q = 360$ km, but $Q \to P = 540$ km. Always read the exact directional value. ### Final Answer Therefore, the correct answer is **240**.
