logic behind it
Jackie made two round trips between two points M & N in a water body. In the first, Jackie rows a streamer with the flow of the stream and he takes 40 seconds. However to go back to the same place against the stream he takes 120 seconds. In the second trip, he took a boat which took 50 seconds to row with the stream and 300 seconds to row against the stream.ย What will be the difference in time taken (in seconds) by Jakie to row the same distance in still water when travelling with streamer and boat? (Write your answer correct up to 2 decimal places)

There are 3 cities A, B, and C which are non-collinear. The number of ways in which one can go from A to B is x. The number of ways in which a person can go from B to C is x2 and the number of ways in which a person can go from A to C is x3. These are the only connected paths. If the total number of ways of reaching C from A is 54, then find the probability that when a person goes from A to C, he chooses one of the paths on the B-C trail.

Hari started working on project somewhere between 3 and 4 PM and completed between somewhere between 8 and 9 PM. The positions of hour hand and minute hand got interchanged at the completion of the project. Find out the time taken by Hari to complete the project. (Write your answer in HH.MM format. So if 4 hour and 50 minutes is the answer then type 04.50)

Analyse the information given below and answer the questions that follow.A1, B1, C1, D1, E1 and F1 are the six bikes displayed in a showroom in a row. Each of the bikes is given individual ranks (ranging from 1 to 6) based on their fuel efficiency and engine strength. For example, in the fuel efficiency category, the most fuel-efficient bike is ranked 1 and the least fuel-efficient bike is ranked 6. Similarly, in the engine strength category, the bike with maximum engine strength is ranked 1 and the bike with minimum engine strength is ranked 6.The following information is known regarding how these bikes are arranged.(i) F1 is displayed to the immediate left of the bike whose engine is stronger than all other bikes except one.(ii) E1 is displayed two places to the right of the second most fuel-efficient bike.(iii) D1 is displayed two places to the left of the third weakest engine bike.(iv) C1 is displayed two places to the left of the bike which is the 3rd most fuel-efficient amongst all.(v) The number of bikes displayed between B1 and F1 is 2, which is the same as the difference between their ranks in engine strength.(vi) A1 is displayed three places to the left of the least fuel-efficient bike and two places to the right of the strongest engine bike.(vii) The most fuel-efficient and least fuel-efficient bikes are displayed next to each other.(viii) The rankings in both fuel efficiency and engine strength are not the same for any bike.Which bike is displayed to the immediate left to A1?
