Directions: In the following question, two statements are numbered as Quantity I and Quantity II. On solving these statements, we get quantities I and II respectively. Solve both quantities and choose the correct option.

Quantity I: A train P of length 500 m can cross a 300 m long platform in 200 seconds. What time it will take to cross another train Q twice of its length running at the same speed in the opposite direction?

Quantity II: A boat in upstream can travel 40 km in 2 hours and in downstream it can travel 60 km in 3 hours. Find the time taken by a car to cross a 1000 m long highway if the speed of the car is the same as the speed of the boat in still water.
