A boat has a speed of 12 km/h in still water and the speed of the stream is 3 km/h. It first covers 45 km in downstream and then travels upstream a distance which is x% less than the downstream distance. If the whole journey takes 5 hours, then find the value of ‘x’.

A 20

B 60

C 85

D 30

E None of these
