The correct option is A 30 km/hr

Let speed of steamer in still water = x km/hr

Speed of stream = 2 km/hr

Speed downstream = (x + 2) km/hr

Speed upstream = (x – 2) km/hr

Distance covered in 7 hours while downstream = 7(x + 2)

According to the condition,

7(x+2) = 8(x-2)

7x + 14 = 8x – 16

x = 30 km/hr
