IBPS PO Prelims 23 Sept 2023 Shift 1 Paper

The total time taken by the boat to go 'x' km upstream and then return back to a certain distance is 6 hours. The ratio of the speed boat in still water to the speed of the stream is 8 : 1, respectively. If the upstream distance covered is 50 km more than the downstream distance covered and the boat can cover (3x + 60) km in still water in 12 hours, then find the value of 'x'?
