Let, the speed of the current be x km/hr Therefore, speed of the boat in still water = 1.25x km/hr Downstream speed of the boat = x + 1.25x = 2.25x km/hr For I: 2.25x = 810/10 => 2.25x = 81 => x = 36 Therefore, speed of boat in still water = 1.25x = 45 km/hr Therefore, I is True. For II: 2.25x = 810/15 => 2.25x = 54 => x = 24 Therefore, speed of boat in still water = 1.25x = 30 km/hr Therefore, II is true. For III: 2.25x = 810/12 => 2.25x = 67.5 => x = 30 Therefore, speed of the boat in still water = 1.25x = 37.5 km/hr Therefore, III is false.
