Question : Two stations R and S are 400 km apart from each other. A train leaves from R to S and simultaneously another train leaves from S to R. Both trains meet after 10 hours. If the speed of the first train is 4 km/hr more than the second train, then what is the speed of the slower train?

Option 1: 18 km/hr

Option 2: 26 km/hr

Option 3: 16 km/hr

Option 4: 22 km/hr

Question : A and B start moving from places X to Y and Y to X, respectively, at the same time on the same day. After crossing each other, A and B take $5 \frac{4}{9}$ hours and 9 hours, respectively, to reach their respective destinations. If the speed of A is 33 km/hr, then the speed (in km/hr) of B is:

Option 1: 22

Option 2: 2

Option 3: $25 \frac{2}{3}$

Option 4: $24 \frac{1}{3}$

Question : X and Y travel a distance of 90 km each such that the speed of Y is greater than that of X. The sum of their speeds is 100 km/hr and the total time taken by both is 3 hours 45 minutes. The ratio of the speed of X to that of Y is:

Option 1: 2 : 3

Option 2: 1 : 3

Option 3: 2 : 4

Option 4: 1 : 4
