Let the speed of the boat in still water and speed of stream be 'x' km/hr and 'y' km/hr respectively. Given, (x - y) = 4 km/hr ATQ, {280 ÷ (x + y) } + {200 ÷ (x - y) } = 70 Or, {280 ÷ (x + y) } + {200/4} = 70 Or, {280 ÷ (x + y) } + 50 = 70 Or, {280 ÷ (x + y) } = 70 - 50 Or, {280 ÷ (x + y) } = 20 So, (x + y) = 14 Therefore, downstream speed of the boat = (x + y) = 14 km/hr
