In the question, two quantities (I) and (II) are given. You have to solve both quantities to establish the correct relation between Quantity (I) and Quantity (II) and choose the correct option.

Quantity (I): A boat takes double the time in covering the same distance in upstream as compared to downstream. If the boat covers 96 km in downstream and 72 upstream in total 20 hours then find the time taken by the boat to cover 240 km in downstream.

Quantity (II): The distance between point 'P' and point 'Q' is 720 km. A car covered 33.33% of the distance at its usual speed and remaining with 20% increased speed. If the car takes total 10 hours 40 minutes to cover the total distance then find in what time the car will cover a distance of 1200 km with its usual speed.
