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 = 315/20 => 2.25x = 15.75 => x = 7 Therefore, speed of boat in still water = 1.25x = 8.75 km/hr Therefore, I is false. For II: 2.25x = 315/10 => 2.25x = 31.5 => x = 14 Therefore, speed of boat in still water = 1.25x = 17.5 km/hr Therefore, II is true. For III: 2.25x = 315/14 => 2.25x = 22.5 => x = 10 Therefore, speed of the boat in still water = 1.25x = 12.5 km/hr Therefore, III is true.
