In the question, two Quantities I and II are given. You have to solve both the Quantities to establish the correct relation between Quantity-I and Quantity-II and choose the correct option. Quantity-I: Train 'A' running at a speed of 180 kmph can cross a pole in t seconds. When the speed of the train is increased by 20%, it can cross a platform of length 300 m in (t + 2) seconds. If another train 'B' of length 1200 metres takes (t + 3) seconds to cross train 'A' when travelling in opposite directions, then find the speed of train 'B' (in km/h). Quantity-II: A train can travel 50% faster than a car. Both start from point A at the same time and reach point B, which is 90 km away from point A, at the same time. On the way, the train stopped for 15 minutes at the stations. If the speed of the car and the train increase by 25% and 20% respectively, then find the difference between their increased speeds (in km/h).
