      Downstream speed of a boat is 16 km /hr. Speed of stream

      is 40% less than the speed of boat. Find the speed of boat?
      A 20 km/h Correct Answer Incorrect Answer
      B 10 km/h Correct Answer Incorrect Answer
      C 60 km/h Correct Answer Incorrect Answer
      D 90 km/h Correct Answer Incorrect Answer

      Solution

      Let speed of boat = x km/h.   Then, speed of stream = x − 0.4x = 0.6x   Downstream speed = boat + stream    ⇒ x + 0.6x = 1.6x   Given 1.6x = 16.   Thus,   ⇒ x = 16/ 1.6 ​= 10 km/h
